## Abstract One can treat the linear variation calculation by the perturbation expansion; on the other hand, one can also relate the perturbed wave function for the __m__th state to the __m__th eigenvector and justify the upper bound nature of the perturbation calculations for excited states. One c
Vector method procedures arr adapted to evaluate Rayleigh-Schriidiiger perturbation corrections to a multiconfiguration zeroth order function. If this function is sufticientiy flexible, this perturbation theory can be applied to low lying excited states\_ The effectiveness of our theory is demonstra
