The infrared spectrum of thiophosphoryl fluoride

Abstract

Investigation of the infrared spectrum of thiophosphoryl fluoride has indicated the following fundamental vibrations: 275, 404, 442, 698, 951 and 983 cm −1. The lowest three frequencies are assigned to deformation modes, the 698 cm −1 band is assigned to the symmetric PF stretch, the 951 cm −1 band to the antisymmetric PF stretch, and the 983 cm −1 band is assigned to the symmetric PS stretching vibration. New thermodynamic functions have been calculated.
