The Beth-Uhlenbeck formula is rederived using the notion of symmetrized and anti-symmetrized partition function introduced by Lee and Yang. By applying the method of complex angular momentum the summation of the phase shifts appearing in the formula is converted into an integral form. Consequently,
A previous method for calculating the second virial coefficients of pure compounds and mixtures is revised. The two empirical constants of a semi-theoretical relation are related to the reduced second virial coefficient values of a pure compound calculated at the normal boiling temperature and at th
