Second-order Møller-Plesset perturbation theory without basis set superposition error : II : open-shell systems
Salvador Sedano, Pedro; Mayer, István
The basis set superposition error-free second-order MØller-Plesset perturbation theory of intermolecular interactions was studied. The difficulties of the counterpoise (CP) correction in open-shell systems were also discussed. The calculations were performed by a program which was used for testing the new variants of the theory. It was shown that the CP correction for the diabatic surfaces should be preferred to the adiabatic ones
