Intratrack recombination in the presence of a scavenger: The role of spatial fluctuations in the location of particles

The simplest model of the kinetics of intratrack inhomogeneous recombination of electrically neutral radicals R + R → R 2 in the presence of a radical scavenger S: R + S → RS, is discussed for the case of a low scavenger concentration. The effect of spatial fluctuations in the arrangement of solute particles on the yield of the recombination product R 2 is examined.
