✦ Synopsis

Two cyclophk~s are studied which contain the same electron donor-acceptor pan but in a different orientation. The transition probability of charge-tiansfer fluorescence and of charge-transfer absorption IS found tc depend strongly on the rektne donor-acceptor oricntatlon. Increese of solvent polarity Ieads to an enhanced radiationless decay of the chargetransfer exated state without a change m its radiative decay rate. The Ltter behaviour contrasts with that reported for intermotecular charge-transfer complexes involving related donor-acceptor systems.

We derive an expression for direct non-radiative electronic energy transfer which accommodates the possibility of a distribution of donor environments. At present we deal with situations in which the sample has a plane of symmetry for the concentration profiles. The relation enables one to evaluate
