We report femtosecond transient absorption spectroscopy of the Fenna–Matthews–Olson (FMO) bacteriochlorophyll complex at physiological temperature (298 K), demonstrating persistent quantum coherence on timescales exceeding 300 fs. Beat-frequency analysis reveals long-lived vibronic coupling between excitonic states, supporting a quantum-assisted energy-transfer mechanism relevant to room-temperature photosynthesis.
