Abstract
Presents a study of the effect of an electric field on the electronic structure of diatomic molecular systems, using the variational method. Some new features which appear in the molecular Stark effect are shown with the help of simple examples. A near-degenerate perturbation scheme is proposed to complement, or replace, the conventional perturbation treatment for internuclear distances where the usual polarisability tensor is not a useful quantity.Keywords
