Abstract

THE ions or molecules occupying the cells of a crystal lattice are in general optically anisotropic, and should also be capable of executing small angular oscillations about their positions of equilibrium. If the crystal is illuminated by monochromatic light of frequency v, the local fluctuations in optical polarization produced by such oscillations should result in scattered radiations appearing with altered frequency, and theory indicates that these should exhibit peculiar polarization characters.
