Raman scattering activities for partially-oriented systems: the case of a unique molecular symmetry axis perpendicular to the uniaxial direction

Raman scattering activities have been derived for the case where the system has uniaxial order imposed on it, but the molecular or factor group's axis of symmetry is perpendicular to the uniaxial direction. The symmetry axis has random ordering about the uniaxial direction around which orientation averaging is done. The expressions for the scattering activities in the molecular co-ordinate system are related to a fixed laboratory co-ordinate system. This is carried out for the three orthogonal orientations of the sample in right-angle and back-scattering geometries. © 1984.
