✦ Synopsis

A new correlation has been developed for calculation of second virial coefficients of polar compounds. The new procedure uses superimposition of the square well potential function and a term accounting for the dipoltiipole interaction. Parameters for this new correlation have been determined for 13 polar compounds. Using these parameters, the second virial coefficients were calculated with a mean standard deviation of 33.68ctn3/gmole or 3&o/,. This compares favorably with the mean standard deviation of Stockmayer's correlation at 31.3 cm'/gmole or 3.36%.

## Abstract An analytical technique based on the method of least squares has been developed to fit experimental second virial coefficients to the functional form derived from the Lennard‐Jones (6–12) potential. Both the functional form and the normal equations of the least squares fit are rigorousl
