Efficient Energy Transfer from the Carotenoid S2 State in a Photosynthetic Light-Harvesting Complex

Previously, the spatial arrangement of the carotenoid and bacteriochlorophyll molecules in the peripheral light-harvesting (LH2) complex from Rhodopseudomonas acidophila strain 10050 has been determined at high resolution. Here, we have time resolved the energy transfer steps that occur between the carotenoid’s initial excited state and t...更多
