Variations of the fluorescence transients were monitored as a function of the excitation fluence and the repetition rate of the excitation. These parameters are directly related to the excitation density within the array and to the number of LH2 complexes that still carry a triplet state prior to the next excitation. Comparison of the experimental observations with results from dynamic Monte Carlo simulations for a model cluster of LH2 complexes yields qualitative agreement without the need for any free parameter and reveals the mutual relationship between energy transfer and annihilation processes. 2011-07-21 00:00:00 LH 2 complexes LH 2 Complexes Rhodopseudomonas acidophila Strain 10050 Studied triplet state LH 2 complexes yields Electronically Excited States energy transfer model cluster repetition rate parameter excitation fluence Phospholipid Model MembranesWe Monte Carlo simulations Dynamic Monte Carlo Simulations II bacterium Rhodopseudomonas acidophila fluorescence transients LH 2 Complexes Reconstituted excitation density annihilation processes
