Reaction centers of Rhodapseudomonas uiridis were studied as a function of pressure using picosecond difference absorption spectroscopy. High pressure increased the rate of electron transfer from P+H< Qa to P+HrQi , measured by the decay of the transient optical absorption Of Hi in the 650-700 nm wa
Electric field effects on reaction centers from Rb. sphaeroides have been detected in ps-transient absorption at 90 K. Upon application of a field of 7 X 10s V/cm the bleaching of the bacteriopheophytin at the A branch (H,, 545 nm) monitored after 30 ps mirrors a reduction of the quantum yield of P+
The picosecond fluorescence kinetics of closed (quinone acceptor QA reduced) reaction centers isolated from the phototrophic bacterium ChloroJlexus aurantiacus shows time constants of 220 and z 300 ps (amplitude ratio = 1: I), which are nearly independent of temperature (7 to 80 K). Assuming a three
