Dear Oliver:

Thanks for your letters.

I have interpreted the o-chlorophenol curves as showing a 22% increased intensity of the weak component as against 28% calculated for 1400 cal/mol ΔH. This seems to me proof of our hypothesis.

May I suggest this action: You be a coauthor with me. Let me put the temperature stuff in, and make a few other small changes, and submit the paper to Lamb. Please answer at once, as I think the paper should be published. The temperature data strengthen[s] it very much, but I can't include them unless you are a co-author. If you have any other high temperature results, let me know.

Have you the second overtone for aniline? We would like to have it very much (or for some amino compound). Mr. Stitt has been doing very well in making calculations on the NH₂ group.

Yours,

Linus

Dear Professor Fieser:

Dr. Wheland and I have decided not to publish our manuscript on naphthalene, although Lamb accepted it for publication. Eyring, as a Referee, wrote "One cannot deny the essential correctness of the arguments of Pauling and Wheland" (Eyring is of course a quantum-mechanics man) but also said "P & W.'s paper is unnecessarily dogmatic and rude". On reading it again, I realize that this is so, and I wish to apologize to you for this.

I realize too that you are right in saying that your paper does not discuss resonance (aside from a brief remark), but rather the different question of tautomerism, and that it provides a valuable contribution in this regard. Our paper was a recapitulation of arguments to show that your results are also compatible with a resonating structure. I would be sorry if you were to ignore resonance completely - perhaps you could devise some chemical method of testing for resonance.

Yours truly,

Linus Pauling

Professor Arthur B. Lamb,

Laboratory of Chemistry,

Harvard University,

Cambridge, Mass.

Dear Professor Lamb:

I wish to submit the enclosed manuscript for publication in the Journal. There is included one figure, taken from the paper of Wulf and Liddel (with their permission). I should like to have the Referee's opinion, as well as your own, as to whether this figure is needed, and whether others should also be reproduced.

Sincerely yours,
