Spectral hole burning study of photosynthetic antenna pigment-protein complexes

Results of persistent spectral hole burning in fluorescence spectra of photosystem II core antenna complexes CP 43 and CP 47 are presented. The holewidths (extrapolated to zero burning fluence) yield the excited state population decay times T 1 which are influenced by fast energy transfer within the...

Description
Summary:Results of persistent spectral hole burning in fluorescence spectra of photosystem II core antenna complexes CP 43 and CP 47 are presented. The holewidths (extrapolated to zero burning fluence) yield the excited state population decay times T 1 which are influenced by fast energy transfer within the antenna complexes. The obtained T 1 values range between 6.6 and 10 ps. The holewidths are independent on temperature within the studied temperature interval 1.5-4.2 K. The observed phenomenon of laser-induced hole filling in the spectra of CP 43 is explained in terms of energy transfer within the CP 43 pigment-protein complex.
