Abstract

Abstract Ring contributions to the third, fourth, fifth, and sixth virial coefficients of the Lennard-Jones (12,6) potential are calculated from the formulation of Montroll and Mayer using the method of Thakkar and Smith for the evaluation of Fourier transforms. An independent check on the calculations is made by calculating C ∗ 3, D ∗ 4 and D ∗ 5 from a different formulation by a combination of Filippi and gaussian quadratures. The two calculations, which agree to six significant figures, resolve the discrepancy between two recent calculations of D ∗ 4 and D ∗ 5 and suggest that the use of multidimensional non-product integration formulae can be hazardous if careful error estimates are not made.
