The Two-Centre Dirac Equation
The description of one or more electrons in the field of two nuclei is one of the fundamental problems in quantum mechanics. Among other things it contains the theoretical understanding of the phenomenon of chemical binding and thus is connects physics and chemistry. In 1927 W. Heitler and F. London1 showed for the first time the possibility of the existence of the H2 molecule. They used an approximation procedure and were able to calculate its physical properties (binding energy, binding length).
