Thermal and Kinetic Analysis

The vapour-phase Raman spectra of the molecules POF3, POCl3, VOF3, VOCl3, PSCl3 and FClO3 have been recorded in sealed tubes at 22–230°C, and accurate values for the fundamentals are reported. The Raman band contours of the e species fundamentals have been analysed to yield Coriolis constants from which e species force constants have been calculated. Raman and infra-red-based Coriolis constants are compared. Values for various thermodynamic functions of the molecules have been evaluated from the new values for the fundamentals, and from the most recent structural parameters.
