Interaction second virial co-efficient of polar-quadrupolar gas mixtures
The interaction second virial coefficient of a binary polar-quadrupolar gas mixtures of non-spherical molecules of arbitrary symmetry has been calculated for a set of unlike force parameters which is obtained from the force parameters for like interactions by using empirical combination rules. In the calculation the influence of anisotropic interactions has been considered. The relative contribution of each branch of interactions has been evaluated as a function of temperature. The theoretical results have been compared with the experimental data of CH3F + N2, CH3F + CO2 and CH3Cl + CS2. The agreement between theory and experiment is satisfactory.
