Raman scattering and the low-frequency vibrational spectrum of glasses.
We present a theory of low-frequency Raman scattering in glasses, based on the concept that light couples to the elastic strains via spatially fluctuating elasto-optic (Pockels) constants. We show that the Raman intensity is not proportional to the vibrational density of states (as was widely believed), but to a convolution of Pockels constant correlation functions with the dynamic strain susce...
متن کاملVibrational modes of partly filled wine glasses
Time-average holographic interferometry has been employed to study how the vibrational modes of a singing wine glass change when it is filled with a liquid. While the liquid clearly lowers the resonance frequencies, it does not change the vibrational mode structure in a first approximation. A more detailed analysis, however, reveals that the presence of the liquid causes the simultaneous excita...
متن کاملPoisson ratio and excess low-frequency vibrational states in glasses.
In glass, starting from a dependence of the Angell's fragility on the Poisson ratio [V. N. Novikov and A. P. Sokolov, Nature 431, 961 (2004)], and a dependence of the Poisson ratio on the atomic packing density [G. N. Greaves, A. L. Greer, R. S. Lakes, and T. Rouxel, Nature Mater. 10, 823 (2011)], we propose that the heterogeneities are predominantly density fluctuations in strong glasses (lowe...
متن کاملCalculation of Low-Frequency Vibrational Modes of Biologically Important Isomers
In this paper we compare the value of different molecular modeling techniques for the prediction of vibrational modes, especially in the midand far-infrared region. There is a wide range of different levels of theory available for molecular modelling—the choice depending on the kind of system to be investigated. For our calculations we use different theoretical approaches such as Hartree-Fock a...
متن کاملLow-frequency vibrational modes of riboflavin and related compounds
The low-frequency vibrations of riboflavin and related compounds (alloxazine, lumichrome, lumiflavin as the ring system and Dmannitol as the side-chain system) were observed by far-infrared (terahertz) spectroscopy. Vibrational mode assignments in this spectrally congested range were made using high precision quantum chemical calculations. These resonance frequencies located below 200 cm 1 indi...
