Abstract

The excitation dynamics in isolated dimers of light harvesting complex I, the peripheral light harvesting complex associated with photosystem I in green plants, was studied by time-resolved fluorescence spectroscopy. A unique combination of two techniques, fluorescence upconversion and synchroscan streak-camera measurements, revealed the energy transfer and decay of excitations over a time range from a hundred femtoseconds up to several nanoseconds, over a spectral range from 570 to 780 nm.
