Fluctuation theory of light scattering

According to the fluctuation theory of light scattering (Flory 1953), the relationship between the Rayleigh factor and the physical characteristics of the macromolecules in solution is expressed in the following general form ... [Pg.499]

The depolarization of light by dense systems of spherical atoms or molecules has been known as an experimental fact for a long time. It is, however, discordant with Smoluchowski s and Einstein s celebrated theories of light scattering which were formulated in the early years of this century. These theories consider the effects of fluctuation of density and other thermodynamic variables [371, 144]. [Pg.367]

The preceding formulas are based on an approximate molecular theory of light scattering. It is more precise to use Eq. (3.2.13), which involves the fluctuations of the spatial Fourier components of the dielectric fluctuations. Although the dielectric con-... [Pg.223]

The relation of fluctuations in concentration to thermodynamic functions was also previously recognized in the theory of light scattering from solutions (Brinkman and Hermans 1949 Kirkwood and Goldberg 1950 Stockmayer 1950) since light is scattered by inhomogeneities in refractive index, which, in turn, arise in part from concentration fluctuations. [Pg.376]

Peter Debye in 1944 further extended the work of Rayleigh and the fluctuation theory of Smoluchowski and Einstein to include the measurement of the scattering of light by macromolecular solutions for determining molecular size. [Pg.112]

Thermal molecular motion is erratic, so that the total scattered field varies randomly at the detector. A recording of this field will look very much like a noise pattern. Hence it is no wonder that the theory of noise and fluctuations is relevant to the study of light-scattering spectroscopy. Before deriving the fundamental formulas... [Pg.10]
