Nonradiative Transfer of Electronic Excitation Energy

Abstract

A chromophore in an electronically excited state can transfer its excitation energy to another chromophore to which it is not in direct contact. The process of energy transfer from an initially excited donor D* to an initially unexcited acceptor A follows the first-order scheme and is described by the kinetic transfer constant k _T $\begin{array}{*{20}{c}} {\mathop D\limits_ \downarrow * + A\;\mathop {\; \to }\limits^{{k_T}} \;\;D + \mathop A\limits_ \downarrow *} \\ {D + hv_F^D\,\,\,\,\,\,\,\,\;A + hv_F^A} \end{array}$
