Abstract:

The total light scattering intensity from a fluid where chemical relaxation takes place via a sequence of coupled reactions is calculated and examined. The fast reaction limiting case where the rate coefficients in one of_the steps are much greater than those in the other step is studied in considerable detail. It is found that only if the reaction is fast and the effective polarizabilities of the species participating in the fast step are equal will the spectrum be simplified. In this case, the broadening of_the Rayleigh peak will be due principally to the slow chemical reaction. When one of the reactions is very fast, the spectrum can be analyzed by assuming chemical equilibrium between the species undergoing rapid reaction.
