Basis set dependent SCα exchange-only and exchange-correlation calculations

Abstract:

The basis set dependent SCα approximation was applied to the LDA, PW91, and B1x exchange functional to form the respective SCα=LDA, SCα-PW91 and SCα-B1x functionals. Both total energies and atomization energies that are quite close to those obtained with the EXX method were obtained, provided that a large enough basis set that allows for a reasonable accurate representation of the molecular orbital was employed. Furthermore, it was shown that the total SCα energies are upper bounds to the EXX ones.
