Abstract
Raman spectra of solid iodine were measured up to 26.8 GPa. New bands observed above 10 GPa are discussed within the framework of a previously suggested quasi-one-dimensional molecular phase existing prior to molecular dissociation. Higher-order spectra due to two- and three-phonon processes were observed up to 10 GPa, and provide information on the pressure dependence of phonon states near the edge of the Brillouin zone.Keywords
