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.
