FIG. 1.

Energy transfer from site i to site f occurs via a direct path with an associated time-dependent amplitude and an indirect path with an amplitude .

FIG. 2.

Chromophores from the structural model of PE545 (Rhodomonas sp. strain CS24). We investigate the influence of PEB 158 C (intermediate site) to the transfer rate from DBV 19 A to DBV 19 B.

Left panel: (a) Lorentzian spectral density of width 50 cm−1 and reorganization energy E R = 110 cm−1. (c) Direct transfer kernel and (e) interference kernel for the Lorentzian spectral density. Right panel: (b) Brownian oscillator spectral density of cutoff frequency ω c = 100 cm−1 and reorganization energy E R = 110 cm−1. (d) Direct transfer kernel and (f) interference kernel for the Brownian oscillator bath. The donor-acceptor energy gap is ω if = 35 cm−1, the intermediate site has an energy of ω mi = 703 cm−1. The relevant electronic couplings are J if = −4.08 cm−1, J im = −31.85 cm−1, J mf = −2.88 cm−1.

(a) The energetics of different intermediate states. The relevant frequencies are ω if = 35 cm−1, cm−1, and cm−1. (b) First-order interference for different intermediate states. (c) Steady-state correction to the transfer rate as a function of the energy of the intermediate site.

FIG. 5.

(a) Brownian oscillator spectral density for different reorganization energies. (b) First-order memory and (c) first-order interference for different bath reorganization energies for the intermediate state |m 1〉. (d) The correction due to the first-order interference relative to the first-order memory as a function of the bath reorganization energy.
