Dexter electron transfer

Schematic of Dexter electron (energy) transfer

Dexter electron transfer (also called Dexter electron exchange and Dexter energy transfer) is a fluorescence quenching mechanism in which an excited electron is transferred from one molecule (a donor) to a second molecule (an acceptor) via a non radiative path.[1][2] This process requires a wavefunction overlap between the donor and acceptor,[3] which means it can only occur at short distances; typically within 10 Å (1 nm).[4] The excited state may be exchanged in a single step, or in two separate charge exchange steps.
