Experimental verification of the Smoluchowski theory for a bimolecular diffusion-controlled reaction in liquid phase

摘要

We report experimental verification of the Smoluchowski theory for diffusion-controlled reactions in solution at the steady-state limit.We have determined both the diffusion coefficients and the self-termination reaction rates of the diphenylmethyl radical simultaneously.Smoluchowski theory is insufficient to discuss the reaction rate for the self-termination reaction of the diphenylmethyl radical,so the reaction rate of an encounter complex based on the Collins-Kimball treatment is estimated.
