Abstract
Analogues of the Murrell—Shaw, Musher—Amos, and van der Avoid—Hirschfelder symmetry adapted perturbation theories are devised for the case of a generalized eigenvalue equation. The new procedures are applied to the hydrogen molecule ion and perturbation energies through second order are calculated at various internuclear distances.Keywords
