Abstract

An equation for the repulsion energy between unlike molecules, which is independent of the form of potential, is obtained from the data on the repulsion energy for like molecules. The equation is based on the model of deformable atoms and on the theoretically substantiated assumption concerning the relation between the closest approach distance and the coordinate of the energy distribution peak for the pair interaction. The applicability of the resultant relation for the known forms of the repulsion potential is considered.
