Inelastic Light-Scattering Study of Macromolecular Reaction Kinetics. I. The Reactions A ⇋ B and 2A ⇋ A2

Abstract: This paper considers the effect of chemical reactions on the spectrum of light scattered from macromolecular solutions. A general formalism is developed, taking into account only diffusion and chemical reaction, using the matrix eigenvalue technique of Salsburg and coworkers. This formalism is applied to the reactions A ^B and 2A

“…The origins of this idea are rooted in chemical relaxation kinetics (13) and in dynamic light scattering (14)(15)(16)(17) on the experimental side and on Onsager's regression hypothesis on the theoretical side. Although elegant theoretical treatments of measurements of chemical reaction kinetics in equilibrium systems by dynamic light scattering had been developed (18,19), experimental measurements were unsuccessful. Dynamic light scattering is an excellent approach for measuring molecular transport in highly purified, relatively concentrated systems.…”

“…There have been many theoretical papers and reviews dealing with light scattering as a probe of chemical kinetics [3][4][5]68] but these investigations have generally emphasized the case where the contribution to the spectrum arises because of polarizability differences between reactants and products. Bloomfield and Benbasat [69] have pointed out that for macromolecules it is the difference in diffusion coefficient between reactants and products that is likely to be more important. Using plausible values of diffusion coefficients and chemical relaxation times, they have demonstrated by way of numerical calculations that light scattering is a feasible approach to the kinetics of macromolecular isomerization and dimerization reactions.…”
