Abstract
The collision integrals and low density viscosity coefficients of n-alkane chains in the range n = 4–9 at several different temperatures have been calculated within the frame of the Mason and Monchick approximation. These computations are based on numerical intermolecular potentials obtained for Monte Carlo samples of pairs of conformations with randomly chosen relative orientations. The conformations are built according to the rotational isomeric model and the interactions are computed assuming a site-site LJ potential, as specified in the preceding paper. The averaged viscosity values are compared with experimental data. From this comparison the consistency of the model and the validity of the method are discussed.
