| Popis: | Resonance Raman (RR) spectra are reported for photosynthetic reaction centers (RC's) from the purple bacterium Rhodobacter sphaeroides. The spectra of quinone-reduced RC's wore obtained by using a large number of excitation wavelengths (23) in the 33S-875-nm range. These wavelengths span the B x , B y , Q x , and Q y absorption bands of the special pair bacteriochlorophyll (P), accessory bacteriochlorophyll (BCh), and bacteriopheophytin (BPh) pigments. The number of exciting lines and their wavelengths were chosen to optimize the selective excitation of the different pigments in the AC and to elicit the full complement of AA scattering from the individual pigments |
