| Abstract: | Starting from the generalized theory of bimolecular diffusion-controlled reactions between reagents in solids and liquids, we have performed calculations of the A + B → AB (Frenkel defect annihilation) and A + A → B (exciton annihilation) reaction kinetics over a wide time interval and for high initial concentrations. The predicted lowering at long times of the reaction rate in the course of the A + B → AB reaction and acceleration at short times of the A + A → B reaction due to dynamical aggregation of similar non-interacting reagents are demonstrated. The possibility of experimental checks of these effects is discussed. |
