Abstract

This work describes a method for the numerical calculation of second and third virial coefficients of simple linear molecules. The method is applied to nitrogen using a two-centre Lennard-Jones pair-potential and the Axilrod-teller term. Values of volumetric and acoustic second and third virial coefficients of nitrogen are reported from 95 – 500 K and compared with the experimental data of several authors. It is argued that the Lennard-Jones potential failed to correlate third virial coefficients because the model neglected dipole-quadrupole and higher dispersion contributions to the pair potential. Keywords: Nitrogen; two-centre Lennard-Jones potential; volumetric virial coefficients, acoustic virial coefficients.
