The photosynthetic apparatus of purple bacteria is a highly efficient system for the conversion of solar radiation into biological usable forms of energy. Part of this photosynthetic apparatus are pigment-protein complexes. They are responsible for the absorption of sunlight and the generation of a stable charge separated state.
We report about ps-time-resolved spectroscopy on ensembles of isolated, i.e. non-interacting, RC-LH1 complexes from Rhodopseudomonas palustris. The experiments are complemented by dynamic Monte Carlo simulations as employed successfully in an earlier study [1, 2].
