The fine structure of the absorption band of P in reaction centers of various phototrophic bacteria has been studied at 1.7-70 K. The vibronic structure with a characteristic frequency of ∼ 140 cm-1, zero-phonon line and phonon wing for the 0-0 transition with relatively weak coupling parameters have been resolved. © 1988.
