Light scattering optical constant

The interesting feature that Lipatov, et al. [1 ] assumed was that the light-scattering intensity at low angles depends on the square of the difference between c and c, which arises from the appearance of (dn/dc) in the scattering optical constant H, noting that the size and shape of the domains is constant with time. Hence,... 

The expressions for scattered light intensity (and Rayleigh ratio) must be corrected by dividing by the appropriate Cabannes factor. Effectively this is equivalent to replacing the optical constant K as defined in Eq. (24) by Kf and by 2 Kfj for unpolarised and vertically polarised incident light respectively. 

B = optical constant of scattering system, depending upon the refractive indices of the solid scatterers and the suspending medium, the wavelength of the light used and the length of the light path ... 

A simple way to determine the relationship between molecular weight and intensity of scattered light is to recast Equation (4.4) by defining an optical constant K using Equation (4.5) and Ro, the Rayleigh factor (Equation (4.6)).
