Calculation of the coefficients of self-diffusion of liquid hydrocarbons in liquid-phase state based on atom-atom interaction potentials

A version of the method of [1–3] for calculating the diffusion coefficients based on the intermolecular potentials is suggested for substances with noncentral intermolecular interactions. The coefficients of self-diffusion of light saturated hydrocarbons are calculated. Good agreement is shown between the theoretical and experimental data.
