Narrator: Dr. Pauling feels that his experiments in x-ray crystallography helped develop his understanding of the atom.
Linus Pauling: I was very fortunate in having A.A. Noyes suggest to me, or tell me, that I was to work with Roscoe Dickinson on x-ray crystallography,
determination of the structure of crystals by x-ray diffraction. This technique gave for the first time detailed information
about how atoms are related to other atoms in a crystal and how far apart they are from the other atoms. I was happy to be
working the way I was, making perhaps small discoveries about the structure of molybdenite and other minerals and inorganic
compounds. And I was eager to understand chemistry better than it was understood in that early period but I didn’t have the
idea, I think, that I was going to be the person that clarified this whole question about the chemical bond.
