N2 - A method is proposed for using isoenergetic configurations formed from many-center Coulomb Sturmians asa basis for calculations on N-electron molecules. Such configurations are solutions to an approximate N-electronSchrödinger equation with a weighted potential, and they are thus closely analogous to the Goscinskianconfigurations that we have used previously to study atomic spectra. We show that when the method is appliedto diatomic molecules, all of the relevant integrals are pure functions of the parameter s=kR, and thereforethey can be evaluated once and for all and stored.
