Single-photon counting techniques were used to measure the fluorescence decay from Rhodopseudomonas sphaeroides and Rhodospirillum rubrum chromatophores after excitation with a 25-ps, 600-nm laser pulse. Electron transfer was blocked beyond the initi

The primary electron transfer processes in isolated reaction centers of Rhodopseudomonas sphaeroides have been investigated with subpicosecond and picosecond spectroscopic techniques. Spectra and kinetics of the absorbance changes following excitatio

Shifts in the absorption bands of bacteriochlorophyll and carotenoids in Chromatium vinosum chromatophores were measured after short actinic flashes, under various conditions. The amplitude of the bacteriochlorophyll band shift correlated well with t

In preparations of photochemical reaction centers from Rhodopseudomonas spheroides R-26, lowering the recox potential so as to reduce the primary electron acceptor prevents the photochemical transfer of an electron from bacteriochlorophyll to the acc

The time-course of fluorescence from reaction centers isolated from Rhodopseudomonas sphaeroides was measured using single-photon counting techniques. When electron transfer is blocked by the reduction of the electron-accepting quinones, reaction cen

Photosynthetic reaction centers isolated from Rhodopseudomonas sphaeroides strain R-26 were excited with non-saturating 7-ps, 600-nm flashes under various conditions, and the resulting absorbance changes were measured. If the quinone electron accepto

Reaction centers from Rhodopseudomonas sphaeroides strain R-26 were prepared with varying Fe and ubiquinone (Q) contents. The photooxidation of P-870 to P-870+ was found to occur with the same quantum yield in Fe-depleted reaction centers as in contr
The rate of the electron-transfer reaction between bacteriopheophytin and the first quinone in isolated reaction centers of Rhodopseudomonas sphaeroides has an unusual temperature dependence. The rate increases about threefold with decreasing tempera

Chromatophores from photosynthetic bacteria were excited with flashes lasting approx. 15 ns. Transient optical absorbance changes not associated with the photochemical electron-transfer reactions were interpreted as reflecting the conversion of bacte
