【 摘 要 】

The fluorescence lifetimes of the reaction centers isolated from the wild-type Rhodopseudomonas sphaeroides purple bacterium and those from the R26 mutant strain, lacking the carotenoid, were measured at low redox potential. In addition to the prompt fluorescence occurring directly from P* and the long delayed emission related to the radical pair state Pf, two other components are present. We suggest that they may come from intermediate states between P* and Pf, or reflect the stabilization of Pf itself.
