On the efficiency of the long wavelength minor bacteriochlorophyll groups in the vicinity of reaction centers.
The role of minor chlorophyll and bacteriochlorophyll groups in excitation delivery to reaction centers and subsequent trapping in them was analyzed by means of PC-modeling. The analysis of general type of photosynthetic units and, in particular, those resembling typical photosystems of purple bacteria, has revealed some types of structures in which the presence of minor BChl fractions in the vicinity of reaction centers did increase the efficiency of the useful energy trapping. In some cases the spectral range of optimal energy conversion is broadened.
