Two Scavengeable Species

In this section, the correction to Smoluchowski s time dependent rate constant is investigated for two scavengeable species using the reaction scheme 

22 Final yield of eS obtained as a function of six different separation distances a 20 A, b 40 A, c 60 A, d 80 A, e 120 A. An Onsager radius of290 A was used in all cases. A mutual diffusion coefficient of 0.28 A ps was used. Here MC refers to random flights simulation 

The conclusion of this chapter is that the rate of scavenging is strongly influenced by the separation of the ion-pair and there is a significant correlation between scavenging and recombination times. In the literature, Smoluchowski s time dependent rate constant is often used to model the scavenging of charged species inside a spur without 

This chapter has shown that a careful handling of both the scavenging and recombination kinetics is required within the IRT framework due to the correlation that exists between them. This dependence of scavenging rate on recombination time is a fundamental breakdown of the assumptions underlying both the theory of diffusion kinetics and the IRT method. Although the effect is mainly noticeable for
