【 摘 要 】

Comparison of the Stark effect on the Q_y transitions of the pigments in reaction centers of Rb. sphaeroides and Rps. viridis at 77 K shows great similarity in the long-wavelength absorption of the bacteriochlorophyll dimer but differs significantly in the absorption region of the accessory bacteriochlorophylls and bacteriopheophytins.
