Linus Pauling: 1931, a simplified theory of hybrid bond orbitals. It took me three years, partially,
a good bit of the time working on determining crystal structures of course but every
once in a while trying to solve that problem about the tetrahedral carbon atom, when
I thought of the, of a simplified theory. The radio part of the wave function of s
and p is much the same as the, for 2s as for 2p in the outer part of the orbital.
So that I said "let's assume they are the same and just look at the angular parts."
