Abstract: The second and third virial coefficient of a gas of nonspherical molecules of arbitrary symmetry have been calculated for a set of force parameters which has been found suitable to explain the dilute gas viscosity data. The influence of a large number of orientation dependent pair- and three-body nonadditive interactions has been taken into account. The relative contribution of each branch of pair and triplet interactions has been evaluated as a function of temperature. The theoretical results have been compared with the experimental data of N2, CO, CO2, CS2, C2H4 and C6H6. The agreement between theory and experiment is very satisfactory for all the systems.
