title = "Coherent nuclear motion and exciton state dynamics in photosynthetic light-harvesting pigment proteins",
abstract = "We have used approximately 40 fs pulses from a Ti:sapphire laser to investigate the ultrafast energy transfer and relaxation dynamics in the light-harvesting pigment-proteins of photosynthetic purple bacteria. Our results reveal two new features, not earlier observed in light-harvesting pigments: (1) ultrafast relaxation characterized by a time constant of approximately 20 fs, which we interpret as interexciton state relaxation; (2) coherent nuclear motions. These new results are challenging the applicability of the `standard' Forster theory to the excitation transfer in photosynthetic antennae which motivated us to examine a more detailed description of the dynamics.",
