A synthesis of high-purity silicon disulfide SiS2 is described, and the F.t.-Raman spectrum of the solid is reported for the first time. The standard massic energy of reaction of SiS2(cr) with fluorine was measured in a bomb calorimeter. The combustion reaction was shown to proceed as follows: SiS2(
new DfHΒ°m (GeS,cr,298.15 K) obtained in Part II of this study (J. Chem. Thermodynamics 1994, 26, 727), yield several derived results for DfHΒ°m(GeS2,cr,298.15 K) that are in reasonable agreement with the calorimetric determinations. The standard molar enthalpy of the transition: GeS2(vit) = GeS2(cr):
Fluorine-bomb calorimetry was used to determine the standard massic energies of combustion \(\Delta_{\mathrm{c}} u^{\nu}\) of the silicon selenides \(\mathrm{SiSe}_{2}(\mathrm{cr}), \mathrm{SiSe}_{1.94}(\mathrm{cr})\), and \(\mathrm{SiSe}_{1.94}(\mathrm{vit})\), according to the combustion reaction:
