Abstract

To solve the problem of the highly excited vibrational-rotational molecular states it is important to construct analytically the perturbation series for the energies and wavefunctions in the Born-Oppenheimer approximation employing such a representation for the potential function which models the nuclear interaction potential with sufficiently high accuracy at large deviations from the equilibrium configuration of the molecule as well as near the equilibrium point. In Refs.1,2 we have conctructed such a series for a diatomic molecule. The nuclear interaction in the zero-order approximation was described by the Kratzer potential
