Photophysical processes in nanosystems exhibit interesting dynamics quite different from those in the bulk. Besides the cage effect, occupancy statistics of excitations becomes important. Since only a few excitations are typically present per nanosys

Energy gap dependence of the electron transfer rate in a system with two distinct classical relaxation modes is discussed. It is shown that when the relaxation slows down, only the fast mode determines the width of the gap-law curve while the positio

A closed matrix form solution of the Bloch–Torrey equation is presented for the magnetization density of spins diffusing in a bounded region under a steady gradient field and for the Stejskal–Tanner gradient pulse sequence, assuming straightforwa

Many donor/acceptor centers are often involved in electron transfer in supramolecular systems with a variety of competitive pathways, either direct or mediated by energetically suitable bridging molecules. In this Letter, complementary to the previou

A stochastic model for migration dynamics of solute molecules from the bulk aqueous phase to the intravesicular water pool is developed with a goal to interpret recent passive permeability measurements of bilayer membranes. Previously neglected fluct

The theoretical basis of the pulsed-held-gradient spin-echo experiment and its applicability to the study of diffusive transport through a spherical interface into an external medium containing a relaxation agent are examined in the long-time diffusi

The exchange of solubilized molecules in microdisperse systems is suggested to occur through successive one-particle hops through fluctuational channels between the droplets during their collisions with temporary merging.The overall transition probab

A theoretical treatment of electronic energy transport and trapping in a finite volume is presented by taking, as a typical example, an ensemble of chromophores solubilized in a spherical micelle. A truncated power series expansion in the chromophore
