Abstract
The thermodynamic properties of sulfur dioxide, carbon disulfide, and carbonyl sulfide are calculated from the molecular constants obtained by electron diffraction and Raman and infrared spectra. — (F0E00) / T298.1 = 50.95, 48.28, 47.39; S0298.1 = 59.40, 56.84, 55.34 for SO2, CS2(g), and COS, respectively. The results are applied to several reactions involving these compounds. The free energies of formation of CS2(l) and COS at 298.1°K are +15.24 and —40.48 kg.cal.
