Reactions in Disordered Media,al kinetic behavior. We consider the time-dependence of the density of particles both in the presence and in the absence of diffusion and focus on pseudounimolecular A(0) << B(0), and on strictly bimolecular A(0) = B(0) initial conditions. In the absence of diffusion, the pseudounimolecular decays a

Localization of Excitonic Eigenstates in Molecular Crystals,iagonal disorders on the exciton wave-functions are analysed through the calculations of inverse participation ratios (IPR) for short-ranged (exchange, octupolar) and long-ranged (dipolar) types of interactions. Configurationally averaged calculations are performed and provide the density and the en

Fusion and Transfer of Triplet Excitons in Isotopically Mixed Naphthalene Crystals,are presented. Exciton fusion in the trap states is investigated by delayed fluorescence emission. Energy transfer efficiency is analyzed by the relative transfer yield to a supertrap acting as a sensor. The temperature dependences observed on delayed fluorescence and on energy transfer are similar,

Concentration Dependences of Homogeneous Broadenings and Cross-Relaxation Rates in Condensed Media:ed distributions. Elimination of interacting species due to either clustering or recombination processes, which do not participate to the processes under study, leads to define effective concentrations instead of sample concentrations. Numerical calculations of these effective concentrations are per
