The Rayleigh ratio, R[theta], represents the relative ratio of the scattered light, taking the angle of scatter and the distance of the observer from the scattering particles into consideration, and it is directly proportional to I/[I.
In static LLS, the angular dependence of the excess absolute time-averaged scattered intensity, known as the excess Rayleigh ratio, [R.
