Heitler, Walter; London, Fritz and Kennard, E. H.

Berlin: Julius Springer. 1st Edition. FIRST EDITION OF THE FIRST APPLICATION OF WAVE MECHANICS TO THE THEORY OF CHEMICAL BONDING.

"In 1927 the Heitler-London theory was formulated which for the first time enabled the calculation of bonding properties of the hydrogen molecule based on quantum mechanical considerations. Specifically, Walter Heitler determined how to use Schrödinger’s wave equation (1925) to show how two hydrogen atom wavefunctions join together, with plus, minus, and exchange terms, to form a covalent bond. He then called up his associate Fritz London and they worked out the details of the theory over the course of the night" (Wikipedia).

ALSO PRESENT: "Zur quantenmechanik einfacher bewegungstypen" by E. H. Kennard – the first mathematically correct formulation of the Heisenberg uncertainty principle. Kennard derived the formula for uncertainty of position and momentum a few months after Heisenberg stated his principle in general terms. Item #26
