Abstract
A relation has been derived between surface tension of pure substances and the parameters of the Lennard-Jones equation for intermolecular potential. The substitution for these parameters from empirical relations makes it possible to calculate the surface tension from critical temperature and critical volume of the substance considered. The derived relation has been verified by comparing the calculated values of surface tensions with the values measured for 22 pure substances.
