Comment On: An Intermolecular Potential for Nitrogen from a Multi-Property Analysis

Abstract

A recent paper by Cappelletti et al. (CVPHD) makes use of classical trajectory (CT) effective kinetic cross sections on an optimized potential energy surface to predict Z for nitrogen gas over a range of temperatures. It is suggested here that an alternative method of conversion between the calculated cross sections and the rotational relaxation quantities (eta nu, the volume viscosity, and Z, the rotational collision number) may give more physically meaningful results.
