Abstract

Light-scattering spectra of powders of transparent materials were found to exhibit a characteristic band at frequencies below ∼1 cm-1. This band was observed in all powdered materials studied, including enzymes, organic and inorganic crystals, and glass. We interpret the band as a superposition of Brillouin lines produced in combined elastic and inelastic scattering events. A theoretical expression is deduced for the spectrum that is in good agreement with the experiments.
