Analysis of a 60-picosecond molecular dynamics trajectory of the reaction center of Rhodopseudomonas viridis provides an understanding of observations concerning vibrational coherence and the nonexponential kinetics of the primary charge transfer in photosynthesis. Complex kinetics arises from energy gap correlations that persist beyond 1 picosecond.
