Scattering constants

Kb, Sb = the absorption and scattering constants of the vehicle (bulk phase of the coating) ... 

Here K is the well known light scattering constant and is defined by... 

The Raman light that escapes the sample will be proportional to the integral of the product of the local power density and the attenuation of escaping Raman light, as in Eq. (6.7) (4). The terms and are the attenuation coefficients for the laser and Raman-shifted light and are generally considered to equal the sum of a scattering constant and an absorption constant, each with units of reciprocal centimeters. 

K is the proportionality constant including instrnment parameters such as laser power J is the scattering constant for the given Raman peak V is the scattering freqnency of the Raman peak c is the concentration of analyte... 

This deduction can therefore better be carried out directly by applying the light scattering formula generally to particles wdth an extra polarizability a and calculating also the mean refractive index with this a. The light scattering constant is then h — 128 Nia /3 and for the mean refractive index n we have...
