Effect of pressure on Raman spectra of solid bromine

Abstract
The effect of pressure on Raman spectra of solid bromine has been measured up to 33 GPa using a diamond anvil cell. Four of six Raman-active modes could be observed in first-order Stokes and anti-Stokes spectra at room temperature. Overlap of the two intramolecular peaks takes place at 24 GPa. The relative scattering intensities of the two intermolecular modes vary with pressure, exceeding finally those of the intramolecular modes.
