Figure 3.

Absorption transients of WT PaBphP and mutants probed at 725 nm with clear oscillation signals. (Left panel) Comparison of exponential (blue) and oscillation (red) fit of experimental data. Note that the oscillation fit begins after 120 fs to avoid the influence of the instrument responses. The insets show the two major oscillation modes derived from the oscillation fit. (Right panel) Fourier transforms of the residuals from exponential fit. The gray dashed lines are the baseline at zero.
