摘要：

Decay-associated (time-resolved) fluorescence spectra of isolated bacteriochlorophyll (BChl) a-containing and BChl a-free chlorosomes were measured using a picosecond single-photon timing apparatus in the detection wavelength range 730 - 820 nm. Two different relaxation steps can be resolved in the energy transfer chain. The first relaxation step occurs within the main BChl c pigment pool and the other is due to the energy transfer from one BChl c pool to the BChl a pool in the so-called baseplate. The corresponding equilibration times are approximately 5 ps and approximately 14 ps respectively. © 1990.
