Mass-spectrometry and Knudsen effusion experiments were used to study the equilibrium partial pressure of SeS formed by reaction of S/sub 2/ and Se/sub 2/ which were produced by thermally decomposing a mixture of In/sub 2/S/sub 3/ and In/sub 2/Se/sub 3/ in a Knudsen effusion cell. The heat of formation of SeS(g) was determined by the second law method to be -0.6 +- 3 kcal/mole. The entropy of formation of SeS(g) was calculated from spectrographic data in Ahmed and Barrow to be 1.5 cal/degree-mole at 298/sup 0/K.
