Abstract A set of improved numerical tables is given for use in calculating the effects of nonspherical molecular interactions on the second virial coefficients of simple molecular gases. The second virial coefficients are given as a spherical-core contribution (not discussed in this paper) plus a series of nonspherical perturbation terms. The tables give easy-to-interpolate auxiliary functions that occur in the perturbation terms. These functions depend on the form assumed for the spherical-core part of the interaction potential, but only in a relatively insensitive way, so that the tables should be adequate for almost all calculations that are likely to occur in this connection. The auxiliary functions J nT are tabulated for n from 6 to 30 and T from 0.5 to 10, where T* = kT/ɛe 0 and ɛe 0 is the well depth of the spherical-core potential. Explicit formulas are given for the simple cases of axially symmetric molecules, but the tabulated functions can also be used for more complex cases.
