【 摘 要 】

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.
