Abstract

The relation of the straightforward Rayleigh‐Schrödinger perturbation theory for the interaction of two atoms to the asymptotic exchange theory is described. The one‐electron case of a hydrogen atom perturbed by a nucleus is examined in detail. It is shown that the asymptotic theory contains an infinite summation of terms in the Rayleigh‐Schrödinger series. The nature of the branching between states and its implications for convergence is elucidated.

A Rayleigh-Schrödinger perturbation theory approach based on the adiabatic (Born-Oppenheimer) separation of vibrational motions was previously developed and used to evaluate for a system of coupled oscillators the adiabatic energy levels and their nonadiabatic corrections. This method is applied her
