Lui & Troisi used the effective-mode Marcus-Jortner-Levich model (Equation ) to study internal conversion in a poly(3-hexylthiophen) to -phenyl-C 61 -butyric acid methyl ester interface and found a rate of 1.93×10 9 s -1 by setting E λ to 0.11 eV. Moreover, they studied the relationship between the rate constant and E λ , and reported a gradient of 6.76 × 10 5 eV -1 . Cerdá and co-workers examine a similar problem for a truxene-tetrathiafulvalene to hemifullerene (C 30 H 12 ) interface, and found internal conversion rate constants from the three lowest charge transfer states to the ground state of 2.6×10 9 s -1 , 1.7×10 5 s -1 , and 2.3×10 4 s -1 , respectively. Bozzi & Rocha used the one-effective mode form of the Marcus-Levich-Jortner model to calculate rate constants for a small number of chromophores, and compared it to classical Marcus theory. Their results (Table ) agree well with experiment for both the one-effective mode and classical Marcus model, however the classical Marcus model is observed to deviate further from experiment than the one-mode Marcus-Levich-Jortner model. In general, classical Marcus theory was found to yield faster rate constants than compared to the effective-mode Marcus-Levich-Jortner model.
