Raman scattering tensors for translational vibrations of ice

Abstract

Summary. --Scattering tensors for the first-and the second-order Raman scattering of light on the translational vibrations of hexagonal ice lattice are related to the crystal space-group Clebsch-Gordan coefficients. Scattered intensities are presented for pairs of phonons allowed by the hexagonal close-packed-crystal selection rules and are discussed for the appropriate light polarizations. The results can be of help in analysis of measurements of polarized light scattering on oriented monocrystals of hexagonal ice.PACS 61.50 -Crystalline state (including molecular motions in solids).
