Figure and Figure show BBPP data for the chromophore and LHC, respectively. In these experiments, the pump and probe laser pulses are identical, having both short (∼24 fs) duration and sufficient bandwidth to excite the molecules to superposition states (ESI). The presence of superposition states is evidenced by oscillations in the signal as a function of time, with a frequency, 𝜔, related to the difference in energy of the states by 𝐸 = ℏ𝜔. Frequency analysis of the BBPP data is shown in the ESI.
