Quantum Yield for Energy Transfer by Resonance

Abstract

The theoretical prediction of quantum yields for electric dipole-dipole energy transfer by resonance is discussed. The common approximation which neglects transfers from each donor to all but the nearest acceptor is extended so as to include transfers to the second-nearest acceptor and, in the limit of very high acceptor concentration, to the third and fourth as well. The total quantum yield and the fractional yields due to transfers to the individual categories of nearest acceptors are evaluated, and the merits of the various approximations are discussed quantitatively.
