Structure and marker mode of the primary electron donor state absorption of photosynthetic bacteria: hole-burned spectra

Structured photochemical hole-burned spectra are presented for P870 and P960 of the reaction centers (RC) of Rhodobacter sphaeroides and Rhodopseudomonas viridis. A special pair marker mode Franck-Condon progression is identified. The zero-phonon holes yield P870* and P960* decay times in good agree...

Description
Summary:Structured photochemical hole-burned spectra are presented for P870 and P960 of the reaction centers (RC) of Rhodobacter sphaeroides and Rhodopseudomonas viridis. A special pair marker mode Franck-Condon progression is identified. The zero-phonon holes yield P870* and P960* decay times in good agreement with the time domain values. Site excitation energy selection is used to establish correlation between a higher energy RC state of Rps. viridis and P960*.
