β¦ Synopsis
Second virid coeffitients for argon are calculated using a pair potentM'det&mined from scattetiigand spcctroswpic data by Parson and Lee. Agreement with experiment is poor. A potential due to Basker, Fisher end Watts agrees about as well as that of Parson and Lee with the scattering and spectroscopic data, and also gives second virial coefficients in excellen: a@vement with experiment.

A general expression is derived for the second vi&l coefficient of a gas of molecules of arbitrary symmetry under the assumption that the anisotropic part of the interaction potential is weak. l3e integral involved in the expression is evaluated in closed form for a Lennard-Jones (6-12) plus long-ra
