Photosynthetic reaction center charge transfer band

How well do observed charge transfer bands fit this simple model The data suggest that the photosynthetic reaction center fits the model reasonably well and allow an extraction of Wg of approximately 200 cm. Cupane et al. also find (for hemoglobin) that the data for band III may be fit, yielding a value of Wg of about 240 cm However, they also find that the case of deoxymyoglobin is more complicated and is not consistent with the simple model. They find in addition that the solvent composition has a strong influence on the nature of the charge transfer band. [Pg.159]

Charge-transfer transitions play an important role in the long-wavelength absorption band of photosynthetic bacterial reaction centers. These pigment-protein complexes cOTitain four molecules of bacteriochlorophyU (BChl) and two bacterio-pheophytins. Two of the BQils are located close together, with their macrocyclic planes approximately parallel and about 3.8 A apart. The center-to-center distance... [Pg.369]
