Light scattering spectrum

Finally, recently depolarized light scattering spectra [191] display an additional process that shows a much faster characteristic time and a much weaker temperature dependence than the dielectric j0-relaxation (more than three orders of magnitude faster time at -200 K and an activation energy of 0.16 eV, about half of the dielectric value). Also atomistic simulations on PB have indicated hopping processes of the frans-double bond [192,193] with an associated activation energy of -0.15 eV. Whether these observations may be related with the discrepancy in the apparent time scale of the NSE and dielectric experiments remains to be seen. 

Several types of collision-induced light scattering spectra are known. We have already mentioned the depolarized translational spectra of rare gas pairs and bigger complexes which arise from the anisotropy of the diatom polarizability. Contrary to the infrared inactivity of like pairs, e.g., Ar-Ar like pairs are Raman active. Furthermore, polarized translational spectra...

Collision-induced light scattering spectra vary with temperature. These variations are of interest because at high temperatures the interactions are probed at smaller separations than at the lower temperatures. An accurate knowledge of the induction operators (i.e., induced trace and anisotropy) over a maximal range of separations is most desirable. Such temperature-controlled studies are just now emerging [197].

Chapter 11 reviews the statistical mechanical basis of hydrodynamics and discusses theories that may be used to extend hydrodynamics beyond the classical equations discussed in Chapter 10. Chapter 12 applies the statistical mechanical theory to the calculation of depolarized light-scattering spectra from dense liquids where interactions between anisotropic molecules are important.
