Excess and interaction second virial coefficients have been measured in the temperature range 290-320 K for 20 binary gaseous systems. Several of these systems have previously been studied by Brewer. The present values are in excellent agreement with his results. The excess virial coefficients have been used to calculate excess molar enthalpies of mixing at 300 K.

Abstract Second virial coefficients of ground state nitrogen atoms have been calculated in the temperature range 6000 - 20000 K. The results have been obtained using experimental potentials for the states 1∑g+, 3∑u+5∑g+ and of the nitrogen molecule and an ab initio Heitler-London potential for the 2∑u+ repulsive potential. Differences up to a factor of 5 are found between the present second virial coefficients and the corresponding values of Kessel'man et al.
