摘要: Abstract Second-order rate constants for the energy transfer reactions between bacteriochlorophyll a lowest triplet and bacterial carotenoids singlet oxygen are reported in benzene as solvent. The results obtained discussed comparison with reaction chlorophyll possibility that steric factors affect of these processes. relevance to vivo photoprotection photosynthetic systems is also discussed.
