Interaction Energies for the H–H2 and H2–H2 System

Interaction energies for the H–H2 and H2–H2 systems have been obtained by a semiempirical perfectpairing procedure used previously. The results have been compared with interaction energies obtained from other sources and the agreement among the different curves is reasonably good. A brief discussion of the previous applications of this semiempirical scheme to other systems is included.
