Abstract
Time-resolved fluorescence spectra and fluorescence polarization anisotropy for monomeric and aggregated chlorophyll a in solution are reported. As well, the separation of fluorescence spectra emitted in time by different chlorophyll species is presented. The study of the anisotropy of separated fluorescence indicate that energy transfer takes place between constituent molecules of the dimer. The high time resolution required in measurements is obtained by using picosecond laser excitation and time correlated single photon counting detection system.
