Persistent photochemical hole burning for P-700 (primary donor state of photsystem I) for enriched reaction center particles is reported. Profiles consisting of a sharp zero-phonon hole superimposed on a very broad hole are interpreted in terms of strong linear electron-phonon coupling. The lifetime of P-700 at 1.6 K is ≈ 90 ps.
