For LO phonons the electrooptic part of the hyper-Raman tensor is found. The results obtained are compared, when possible, with experimental and theoretical data reported in the literature.doi:10.1016/S0022-3697(03)00238-5W. KucharczykF.L. Castillo Alvarado...

Hyper-Raman tensors are obtained through the application of finite electric fields and explicitly account for the nonlinear modulation of the dielectric susceptibility by longitudinal vibrational modes. We apply our scheme to a model of vitreous silica in various scattering geometries and polarization ...
In this paper, using the 伪-helical polypeptide symmetry as an example, we calculate all the third rank nonzero hyper-Raman tensors as well as the infrared and Raman tensors by applying the projection operators to each irreducible species. We demonstrate that the projection operator method ...

In order to calculate relative intensities of vibration-rotation lines in hyper-Raman spectra, line strengths are introduced and these are calculated using the method of irreducible spherical tensors. It transpires that the hyper-Raman effect caused by scattering of a quasi-monochromatic light beam ...
The dipolar molecules both exhibit depolarization ratios of for resonance Raman and 蟻=1/5 for hyper-Rayleigh and hyper-Raman, consistent with the polarizability and the hyperpolarizability tensors having a single non-zero element. The resonance hyper-Rayleigh scattering from both of the octupolar ...
Consequently, the vibrational hyper-Raman selection rules for such species are governed solely by a fully symmetric hyperpolarizability tensor and it is predicted that vibrational hyper-Raman scattering from octahedral molecules is very weak.doi:10.1016/j.cplett.2008.05.004Trevor J. Dines...
