Linus Pauling: I put this slide in of hexamethylenetetramine to show tetrahedral character, the tetrahedral character of atoms. The six
carbon atoms are tetrahedrally bonded to the neighbors and the four nitrogen atoms have bonds at three tetrahedron corners
to the carbon atoms. This is the first structure of an organic compound to have been determined precisely, the bond lengths
and bond angles. It was...done by Roscoe Gilkey Dickinson, x-ray crystallographer with whom I began my graduate work in Pasadena
in 1922, who taught me the science of x-ray diffraction of, by crystals for the determination of their structures as it was
practiced then. It was a very powerful, valuable technique this x-ray diffraction, and of course after awhile other organic
compounds as well as inorganic compounds began to be determined.
