Annihilation sequential

Unfortunately the straightforward comparison of the present theory with those data is hardly possible because in the real experiments the distribution of reactants is not homogeneous. The counterions are injected sequentially from a common electrode. Their local densities differ significantly from each other and change with time as a result of not only the reaction but also their spatial diffusion out of the electrode. There are also some doubts as to whether the annihilation is the only mechanism of triplet quenching. The latter can be carried out in encounters with ions as well [279,280]. These channels of additional recombination can be taken into account but only for the homogeneous solution [194]. Hence, the problem remains open for further discussion.
