Abstract. The goal of this work is to prove the applicability of the isotropic temperature-dependent potential (ITDP) to some polyatomic globular molecules and to obtain reliable data for their transport and equilibrium properties. The four parameters of this effective Lennard-Jones type potential are determined by minimization of the weighted sum of squared deviations between experimental and calculated viscosity and second virial coefficient data.
