Interpretation of Light Scattering Experiments

For the quantitative analysis of the scattering data the concentration and the refractive index increment of the scattering entities must be known, which can be calculated after the determination of the PEC stoichiometry from the corresponding values of the components. 

Characterizing the complex particle systems we are confronted with two problems  

Recently a simple fitting algorithm was derived by us [28,29], based on following ideas  

The results of model calculations can be represented ip a scaled manner for all kind of plots, which are proposed in the literature and are given by the expression

The asymmetric diffusor problem is much more complicated than that of the symmetric diffusor. We give here only a brief indication of how the results are obtained—referring the reader to the literature for the details (Favro, 1960). Since the results are important in the interpretation of light-scattering experiments we present them in full. 

Of course there is no a priori reason for g = 0. Equation (12.3.27) provides a useful interpretation of light-scattering experiments. In principle (1 + Nf) can be determined from integrated intensities.8 Ty can be determined from the spectral width xs can be determined from an NMR experiment or other method, and Eq. (12.3.29) can then be used to find g.
