Abstract

Zero-phonon, vibronic, and phononic satellite hole structure are reported for a core antenna complex (C670) of photosystem I. The electron-protein phonon coupling of C670 is compared with that for the primary electron donor state P700. Low-frequency phonons (∼30 cm-1) are implicated as the primary acceptor modes for excitation transport from the antenna to the reaction center. Excitation transport within the antenna at helium temperatures is markedly slower than at room temperature.
