Rayleigh ratio, solution particles

Static Light Scattering. For a solution of polydisperse nonabsorbing particles, the Rayleigh ratio Rvv(9) is the excess absolute scattered intensity of the solution over that of the pure... 

For the convenience of discussion, both macromolecules and colloidal particles are referred to as particles hereafter. When a light beam Zinc hits a solution, the excess Rayleigh ratio Ryyiq) of the solute particles for the vertically polarized incident and scattering lights has the form... 

R( The excess Rayleigh scattering factor defined as the Rayleigh ratio of the solution or single particle event from which is subtracted the Rayleigh ratio of the carrier fluid along with any other background contribntions. 

In studies of macromolecules or small particles in solution or suspension, the excess Rayleigh ratio is often used to characterize the absolute scattered intensity. The excess Rayleigh ratio is defined as ... 

Consider a dilute one-component solution of particles with a molecular weight distribution expressed by the distribution function u/(M), which is defined such that the weight frartion of particles of molecular weight between M and M + dAl is given by u/(M)dM. Then, for such a system, the excess Rayleigh ratio is given from eqn [26] as...
