Abstract

Multicenter overlap integrals appearing in the evaluation of multicenter-multielectron integrals of central and noncentral interaction potentials are calculated using complete orthonormal sets of Psi(alpha)-ETOs (alpha=1, 0, -1, -2, ...). The final results are expressed in terms of two-center overlap integrals between STOs. The convergence of the series is tested by calculating concrete cases for arbitrary quantum numbers, screening constants and location of STOs.
