  June 2, 1943

  Dear Mom,

  I am glad to find that you and Daddy are taking off for a little vacation. It's time you had some rest.

  I'll probably wander south about the 12^th of June. Much depends on my military activities. On Tuesday I went to the Army Air Corps Cadet Selection Center in S.F. and took the mental exam, which consists of 150 questions, America average approximately 75 right, passing grade for Air Corps 80, and a three hour time limit. I managed to get a score of 125 in an hour and a half. It was a rather simple test. Tomorrow I leave at 7:30 A.M. for Hamilton Field for my final physical exam. I'm not too worried about passing that because my visual acuity and color perception were tested before I took the exam and everything was O.K. It will take a couple of weeks for papers to get through, and then I'll be inducted. After induction I get sent home for another week to await orders. The Santa Ana probably. Some fun.

  Those cookies were wonderful. The diet we get here is foul, especially now , as the cook is worried about being in the hole as regards points. I haven't had nearly enough fresh foods, so my health is somewhat run down.

  Please send me the June $50. I have to move out of the house on Saturday, so please send mail to the Millers at 1709 Gough Street, S.F. if I get any communications from the Government, you might open them to see if there is anything urgent.

  A fraternity brother of mine and extremely brilliant character, 2.8 average (corresponds to an A- approx) I.Q. 139, wants me to go on a little spree with him in the south land San Diego, etc. but I don't' know that I'll have time.

  Give my love to that sweet little sister of mine, and to Pete and Crellie, too. I'll write again and relate the latest developments.

  Love,

  Linus

  P.S. She has beautiful, soulful, brown eyes, with flecks of green!

  Dr. L. Michaelis

  Rockefeller Institute for Medical Research

  66th Street and York Avenue

  New York, New York

  Dear Dr. Michaelis:

  I am very much interested to learn that you could not verify the work of Wagner and Grunewald, and believe now that quinhydrone does not exist in solution.

  I am not sure that I have mentioned it in earlier letters, but I may say now that I would not think that the methyl groups in duroquinone would interfere with a plane-to-plane structure, since the diameter of a methyl group is just about equal to the thickness of a benzene ring. On the other hand, if it be assumed that in quinhydrone the O-H-0 bond is coplanar with the ring, about 2.6 Å long, and at an angle with the 0-0 bond of about 120º (the angle may well be less), the calculated distance from the oxygen of one molecule to an ortho-methyl group is 2.5 Å, and that to an ortho-hydrogen somewhat larger, about 2.7 Å. The sum of van der Waals' radii for oxygen and methyl is about 3.5 Å and for oxygen and hydrogen about 2.5; accordingly we see that duroquinone would not be expected to form a quinhydrone, whereas ordinary quinhydrone should be stable, there being no steric- hindrance.

  With best regards, I am

  Sincerely yours,

  Linus Pauling

  June 9, 1943

  Dr. M. A. Peacock

  Department of Mineralogy

  University of Toronto

  Toronto 5, Canada

  Dear Dr. Peacock:

  Your letter has tempted me to think some more about your crystal Ni3Bi2S2, even though I should be devoting my time to other things. I have finally decided that this crystal, like many others containing bismuth and sulfur, must contain Bi-S-Bi-S-Bi-S- strings, connected with covalent bonds. The Bi-S distance would he 2.50 Å or slightly larger, perhaps as large as 2.60 Å, corresponding to a covalent bond. The bond angle for sulfur would be expected to be about 105°; that for bismuth would be uncertain, because of the fact that the electronic structure must be such as to correspond to an increase of the shell beyond an octet for bismuth. Presumably the bismuth atom has three unshared pairs of electrons and forms two covalent bonds, a total of ten pairs of electrons. It is probable, however, that with this electron configuration the bond angle for bismuth would also be around 100°. The Bi-S distance 2.50 Å corresponds, with the lattice constant a0 equal to 4.02 Å to a bond angle for both sulfur and bismuth of 105°. This is, then, completely reasonable.

  I have studied thoroughly the possible ways of introducing this chain, and I have not found any satisfactory way except by having the sulfur atoms also form a covalent bond with one another. This leads to what seems to be a reasonable structure. If we divide the unit cell up into four quadrants, as shown on the attached sketch, then we can bring the sulfur atoms together, to within 2.1 Å of one another, in one of the quadrants. The sulfur atoms are at (½,y,z¯) and (½,½y¯,½z+) with y = O.063 and z = 0.26. Then nickel atoms would be put in the centers of the other three quadrants, as you have done. This would surround the first nickel atom with four bismuth atoms at 2.82 Å, two nickel atoms at 2.86 Å, and two sulfur atoms at 1.75 Å. The last of these distances is too small, and I think that perhaps this nickel atom may be at the positions occupied by sulfur in your structure instead. The other two nickel atoms are in the positions you assign them. Why don't you try calculating intensities for structures of this sort, shifting the nickel atoms around among the possible positions.

  Ten or twelve years ago I was planning to make a study of the sulfide minerals, but I abandoned the plan. I am interested to see the work which you and Mary have done on cell dimensions of some of these minerals. Have you noticed that those containing bismuth and sulfur usually have a dimension along a fiber axis of 4.05 ± O.05 Å? I think that this indicates the presence in them of the same Bi-S-Bi-S-Bi- chain described above.

  The compound PdBi2 presents an interesting problem. I suggest that it consists of layers 2Bi-2Pd-2Bi----2Bi-2Pd-2Bi----, each layer 2Bi consisting of a puckered Bi-Bi-Bi-Bi- chain similar to that described above, with Bi-Bi equal to 3.0 Å and bond angle about 100 or 105°. These chains would stretch along the 4.28 Å axis, in the plane 100. Two such bismuth layers would be held together by a palladium layer midway between them, each palladium atom presumably having six bismuth neighbors at 2.9 Å. A structure of this sort accounts for the good cleavage and the subsidiary cleavage, and for the intensities of reflection from the basal plane 100. I think that the β modification probably contains essentially the same layers.

  I shall be interested to know how you get along with your structure determinations.

  Sincerely yours,

  Linus Pauling

  Dear Doctor Pauling:

  We are safely Back in the windy and warm city of Chicago and remember with some regret the cool nights in Altadena.

  I hope you and Mrs. Pauling had an enjoyable vacation. It was good of you to have had us to your home and we are quite envious of your wonderful view and all that goes with it.

  You have my good wishes in your endeavor to prepare artificial antibodies, but I must confess a feeling of pessimism in regard to this problem. I cannot help but believe the attempt to be premature. We do not know what configurations on the surface of the globulin molecule are necessary for antibody properties, nor do we know how to produce a given surface configuration even if we knew the one we wanted. In short, any success one might have must be regarded as just plain luck. Frankly, I am not impressed by experimental procedures which work sometimes but which do not at other times, and no cause can be assigned for the failure. No doubt you are as well aware of this as I, but I thought it best to put it down for what it is worth.

  If the experiments on heating at 57°C. are to be continued, I suggest that concentrated solutions of antigen and of serum globulin be used. In fact, I should think the favorable condition would be to dry a mixture of antigen and of globulin down in somewhat the same manner as Dr. Wright and I did and then hold this material at 57°C. for the desired length of time in a moist atmosphere.

  Another experiment which might be worth trying would be to mix with the antigen and globulin some urea and have the concentration of urea such that when the mixture is dried down, it will be about

  -2-

  8 molar. You can count on about 35 to 40 per cent water remaining if the relative humidity be held near unity. Upon resolution, sufficient water is to be used so that there will be no further action by the urea. I hope these two suggestions may prove of some use to you.

  There is a matter which I wanted to ask you about before my departure from Pasadena, but I didn't get around to it. We would like to have Swingle and Wright make an electrophoresis cell for us. They both agreed to construct such a cell providing they had your permission. They felt that $75.00 would be sufficient to reimburse them for the trouble. I should like to hear from you in regard to this.

  Both Mrs. Bull and myself thoroughly enjoyed our visit to California; please accept our sincere thanks for making the visit possible.

  Sincerely yours,

  Henry B. Bull

  Dear Dr. Thomas:

  I make the following report on the problem of diethyl benzene in ethyl benzene.

  There seems to be no possibility of concentrating or isolating diethyl benzene in this mixture by direct chromatography, because of the fact that no suitable adsorbent is known. I asked Professor H. J. Lucas whether or not any reaction could be suggested by means of which the two substances could be converted into derivatives which could then be chromatographed. He has reported to me that reaction with SO2C12 plus a small amount of added peroxide (Kharasch and Brown, J.A.C.S. 6l, 2144 (1939) would in a few minutes give side chain chlorination. This might be carried out in such a way as to chlorinate both side chains in the diethyl compound. In this case a chromatographic separation might be carried out. It might be possible to devise a simple colorimetric method of determination of the chlorinated diethyl benzene after its separation.

  If you have facilities available, why do you not carry out a test of this procedure. If you think that this is promising, and that the work is important, we could probably arrange to have it done quickly here.

  Sincerely yours,

  Linus Pauling

  Dear Dr. Bull:

  I am sorry to say that my wife and I have not, because of our duties here, been able to get away on a vacation. I am still hoping that we can take a few days off.

  I do not agree with your idea that the manufacture of artificial antibodies should be delayed until information about the configuration of the surface of the globulin molecule is at hand. If we need to know about the structure of proteins before working with proteins no protein experiments at all could be carried out. I agree, of course, that experiments aren't worth very much until they are reproducible.

  Thanks for your suggestions about experiments to be carried out.

  I shall be glad to see the report on your work, when you get time to prepare it and send it to me. I understand that it is not satisfactory for publication, but I need to have a detailed account of the work in order to plan what should be done next and to avoid duplication of effort.

  Sincerely yours,

  Dear Dr. Michaelis:

  I feel some concern about your statement in your letter of June 15 that in the quinone-hydroquinone system where there is the possibility of complete resonance, the proton is in the average equidistant from the two oxygen atoms. In a certain sense this is presumably correct; however, this statement might be interpreted as meaning that the stable position of the proton is midway between the two oxygen atoms, which is, I think, not so. It is very probable instead that the proton is practically always much nearer to one oxygen atom than to the other. This point is discussed in Section 38 of THE NATURE OF THE CHEMICAL BOND. In view of the fact that the frequency of motion of the proton from one equilibrium position to another would be very small, and hence that the resonance energy resulting from this motion would also be very smell, the symmetry of systems involving hydrogen bonds is not so significant with respect to resonance energy as the symmetry of systems involving electronic resonance.

  I am completely satisfied with the situation regarding acknowledgment of my suggestion. I am not discussing scientific matters with you because I want to get acknowledgement, but in the hope that I can be of some use to you in connection with your work. I shall continue to send my opinions to you, in the hope that you may find some of them useful.

  Sincerely yours,

  Dear Doctor Pauling:

  I am enclosing a report on the research on the production of artificial antibodies which I carried out during the spring quarter at Pasadena. Dr. Wright took an active part in these experiments and his suggestions and aid were most helpful.

  Well, perhaps you are right about the possibility of production of artificial antibodies; however, I must say that I am glad it is your and Dan's baby and not mine. Best of luck, and if in my wanderings around in the field of proteins, I turn up something which might prove of value to you, I'll send it to you.

  I am wondering what your reaction might be to having Swingle and Wright make up an electrophoresis cell for us.

  June.30, 1943

  Dear Mrs. Landsteiner:

  It is with a feeling of very great personal loss that I have learned of the death of Dr. Landsteiner. He has been one of the great men of our age not only in his own contributions to science and human welfare but also in his influence on other people, and especially on younger scientists. My own debt to him is very great - my work in recent years not only has been based on Dr. Landsteiner's researches, but also resulted directly from his direct inspiration and encouragement.

  I extend to you, dear Mrs. Landsteiner, my heartfelt sympathy.

  Sincerely yours,

  Linus Pauling
