Laser Light Scattering from Liquids
Many detailed reviews of laser scattering from fluids (1-16) have appeared since the comprehensive review by Chu (1) in this series. Among these, we would like to call attention to those by Swinney (14) on critical phenomena, by Gelbart (13) on collision-induced phenomena, by Pecora (7) on macromolecules in solution, and by Fleury & Boon (12) on the overall field of scattering from fluids. Over...
متن کاملLight-scattering spectra of supercooled molecular liquids.
The light-scattering spectra of molecular liquids are derived within a generalized hydrodynamics. The wave-vector and scattering-angle dependencies are given in the most general case and the change of the spectral features from liquid to solidlike is discussed without phenomenological model assumptions for (general) dielectric systems without long-ranged order. Exact microscopic expressions are...
متن کاملDynamic light scattering in mixed alkali metaphosphate glass forming liquids.
We report the first ever photon correlation spectroscopy performed on single alkali and mixed alkali metaphosphate glasses at refractory temperatures above the glass transition. We find not only a significant decrease in the glass transition temperature but also a decrease in fragility for the mixed alkali composition as compared with the single akali glasses. We argue that structural relaxatio...
متن کاملLight scattering by cubical particle in the WKB approximation
In this work, we determined the analytical expressions of the form factor of a cubical particle in the WKB approximation. We adapted some variables (size parameter, refractive index, the scattering angle) and found the form factor in the approximation of Rayleigh-Gans-Debye (RGD), Anomalous Diffraction (AD), and determined the efficiency factor of the extinction. Finally, to illustrate our form...
متن کاملscattering in rare - gas liquids
The Rayleigh scattering length has been calculated for rare-gas liquids in the ultraviolet for the frequencies at which they luminesce. The calculations are based on the measured dielectric constants in the UV in the gas phase, in some cases extrapolated to the wavelength of luminescence. The scattering length may place constraints on the design of some large-scale detectors, using UV luminesce...
