He kept working for hours. Using the same basic approach, he found he could add more
electrons to his calculations and derive the features of more and more complex molecules.
The ability to hybridize the physicists' subshells into new orbitals opened the door
to explaining the structure of a number of molecules, such as the bonding pattern
found in certain cobalt and platinum compounds. One by one, under Pauling's pen, the
physicists’ quantum mechanics was falling into line with what the chemists knew to
be true.
"I was so excited and happy, I think I stayed up all night, making, writing out, solving
the equations, which were so simple that I could solve them in a few minutes," he
remembered. "Solve one equation, get the answer, then solve another equation about
the structure of octahedral complexes such as the ferrocyanide ion in potassium ferrocyanide,
or square planar complexes such as in tetrachloroplatinate ion, and various other
problems. I just kept getting more and more euphorious as time went by."
