Abstract
Infrared and Raman spectra of Engel's sulfur S6, including complete polarization data for solutions of S6, provide assignments for the fundamental modes. Force fields that have been successful for S8 provide good agreement with the S6 spectra. A force model previously used for S8 is shown to be incorrect. Thermodynamic properties (HT°—H0°, FT°—H0°, ST°—S0°) for gaseous S6 are tabulated from 100° to 3000°K. The spectroscopic values S400° (92.8 eu) and S298° (84.6 eu) are in excellent agreement with those derived from thermodynamic measurements.Keywords
