Raman Spectra for XeF2, XeF4, and XeOF4 Vapors, and Force Constant Calculations

Abstract

Raman spectra of the vapor phase have been observed for XeF₂, XeF₄, and XeOF₄. These, together with published infrared spectra, provide vapor values for all but one of the 19 vibrational frequencies of these three molecules. Normal coordinates and force constants are determined in terms of the orbital valency force field model, including repulsions between lone‐pair electrons and fluorine atoms.
