General theory of the excitation energy transfer EET in the case of donor-mediator-acceptor
system was constructed by using generalized master equation GME. In this theory, we consider the
direct and indirect transitions in the EET consistently. Hence, our theory includes the quantum
mechanical interference between the direct and indirect transitions automatically. Memory functions
in the GME were expressed by the overlap integrals among the time-dependent emission spectrum
of the donor, the absorption spectrum of the mediator, the time-dependent emission spectrum of the
mediator, and the absorption spectrum of the acceptor. In the Markov limit of the memory functions,
we obtained the rate of EET which consists of three terms due to the direct transition, the indirect
transition, and the interference between them. We found that the interference works effectively in
the limit of slow thermalization at the intermediate state. The formula of EET rate in this limit was
expressed by the convolution of the EET interaction and optical spectra. The interference effect
strongly depends on the width of the absorption spectrum of mediator molecule and the energy gap
between the donor and the mediator molecules.

*Advanced Theory of Excitation Energy Transfer in Dimers 査読有り

Previously, we developed a unified theory of the excitation energy transfer (EET) in dimers, which is applicable
to all of the cases of excitonic coupling strength (Kimura, A.; Kakitani, T.; Yamato, T. J. Phys. Chem. B
2000, 104, 9276). This theory was formulated only for the forward reaction of the EET. In the present paper,
we advanced this theory so that it might include the backward reaction of the EET as well as the forward
reaction. This new theory is formulated on the basis of the generalized master equation (GME), without
using physically unclear assumptions. Comparing the present result with the previous one, we find that the
excitonic coupling strengths of criteria between exciton and partial exciton and between hot transfer and
hopping (Fo¨rster) mechanisms are reduced by a factor of 2. The critical coherency èc is also reduced
significantly.
