The value of rough quantum mechanical calculations

Abstract

During a few years beginning in 1927 rough quantum mechanical calculations of the energy of the ground states with simple wave functions based upon certain models were made for H 2 + , H2, and He 2 + . These calculations provided much insight into the nature of the chemical bond, a concept formulated empirically in the 19th century, and of the chemists' classical valence-bond theory, also formulated in the 19th century. Moreover, ideas suggested by the rough calculations permitted the valence-bond theory to be greatly refined and made more powerful. Extensive knowledge about the properties of atomic nuclei was obtained only after quantum mechanics had been discovered. Nuclear physicists have for the most part striven to carry out very accurate quantum mechanical calculations of nuclear properties, with results that are often in excellent agreement with experiment. I suggest that rough calculations based on simple models might give additional insight and suggest new experiments.
