[Study of microwave photolosses in chromatophores of photosynthesizing Rhodospirillum rubrum bacteria]. / Issledovanie mikrovolnovykh fotopoter' v khromatoforakh fotosinteziruiushchikh bakterii Rhodospirillum rubrum.

The study of photoinduced dielectric losses at frequency 10(10) c/s as function of samples humidity, heating and chemical treatment, intensity and wavelength of light is reported. The signals of microwave losses and differential spectrum signals are compared. The authors attribute the photolosses observed to the electrons localised in the realm between the primary and secondary acceptors during their reduction, probably being in the conductance quasiband of proteins in the photosynthetic reaction centre.

[Charge transfer in the primary processes of photosynthesis]. / O perenose zariada v pervichnykh protsessakh fotosinteza.

Transmission of electric charges generated by light in the unbranching chain of electron transport is under consideration. Recombination of electrons and holes and possibility of reverse processes are considered. Expression for the efficiency of steady-state charge separation is obtained. Example of the reaction centre of bacterial photosynthesis is considered. All this permits to connect the signals of microwave photolosses with the destination of the electron on distant electron carriers.
