Interaction-optimized virtual orbitals: III. Single excitations

Abstract

Interaction-optimized virtual orbitals are presented for single excitations from a closed-shell reference function. Numerical calculations which use this type of virtual orbitals are presented for the interaction of boron trifluoride with carbon monoxide. The results of these calculations are consistent with the observations of a van der Waals complex in supersonic molecular beams.
