## Rayleigh-Schr6dinger variational pertxhation theory is applied to the hydrogen-like atom with a perturbation proportional to l/r. It is r&orousIy shown &t the e.xact eigenfunction is obtained by direct summation of the perturbation ezqansion through infinite order.
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
