Abstract : A Knudsen-Torsion effusion apparatus was developed which permits the study of a two-species gaseous equilibrium system at variable pressures and high temperature. In particular, this apparatus is suitable for the determination of the dissociation energies of S2, Se2 and Te2. The dissociation energy of diatomic sulfur, obtained by this method is 76.46 - 1.36 kcal. This value shows that the spectroscopically observed dissociation of diatomic sulfur is into the one normal and one excited atom.
