title: [Delayed bacteriochlorophyll luminescence and the primary stages of electron transport in photosynthetic reaction centers of purple bacteria].
abstract: The results of studies of charge separation in photosynthetic reaction centers of purple bacteria are summarized. The findings concerning the sequence of initial steps of the electron transfer and properties of the electron carriers obtained by direct methods of differential optical absorption and ESR spectroscopy are compared with the data on the bacteriochlorophyll delayed fluorescence resulting from reversal of charge separation. The data analysis gives an integrated description of the reaction center operation which is not avoid of discrepancies.
