. In it the 30 year old Pauling explained the tetrahedral coordination of carbon and the square or octahedral coordination of transition-metal ions on wave mechanical principles. He introduced the concept of hybridization and his rules provided information regarding the relative strength of bonds formed by different atoms, the angles between bonds, free rotation or lack of free rotation about bond axes and a complete theory of the magnetic moments of molecules and complex ions.
This paper was published on 6 April 1931. On 7 April, Pauling sent off a one page summary of that paper entitled `Quantum Mechanics and the Chemical Bond' to Physical Review, who published it on 1 May. Such was the confidence, clarity and compelling urgency that animated Pauling in his early days - these qualities never deserted him.
