Some a priori bounds for the error of the QSSA approximation in spatially distributed systems are obtained. The error bounds obtained, depend on the spatial and temporal characteristics of the solution of the reduced system obtained with the use of the QSSA.
The observation of coherent triplet Frenkel excitons is reported in a molecular crystal 1,2,4.5 tetrachlorobenzene. The results can be interpreted in terms of a one-dimensional model in which the largest intermolecular exchange interaction is associated with the translationally equivalent molecules
A theory of microwave band-to-band transitions in triplet Frenkei excitons in the coherent migration limit for a one-dimensional exciton associated with translationally equivalent molecules is developed. Because of selective spin-orbit coupling to the maw\_ tic sublevels, an anisotropy in the zero f
