Abstract
Using a Raman tube made of the plastic polychlorotrifluoroethylene, the Raman spectrum of bromine pentafluoride has been obtained. A method has been developed for making polarization measurements when Raman tubes constructed of this plastic are used. The spectrum of bromine pentafluoride has been correlated with a tetragonal pyramid configuration with symmetry C4v. Force constants were calculated using the Wilson FG Matrix method. The thermodynamic functions for BrF5 were calculated for temperatures ranging from 313.7°K to 1500°K, using the rigid rotator, harmonic oscillator approximation.Keywords
