Intermolecular potential functions for the Ne-N₂ interaction

Abstract

The intermolecular potential energy function for the Ne-N₂ interaction has been studied. New ab initio calculations of the short range energy have been carried out and these form the basis of the repulsive part of the potential. The long range potential uses published results for the dispersion energy coefficients and various types of damping function have been applied to the dispersion energy at medium and short separations. The best overall forms of potential have been assessed by critical comparisons with experimental results for the interaction second virial coefficients and the low pressure viscosity and diffusion coefficients.
