Laser Raman Spectra of Liquid and Solid Bromine and Carbon Disulfide Under High Pressure

Abstract

Liquid and solid phase Raman spectra of bromine and carbon disulfide were obtained at high pressure in the diamond cell. Single crystals of both compounds were grown under high pressure and polarized Raman spectra obtained. These spectra indicate that the splitting of the symmetric stretching vibration in solid bromine may be due to intermolecular coupling (factor group splitting). The observed splitting of this vibration in liquid and solid carbon disulfide is most likely due to contributions from naturally occurring sulfur isotopes.
