    • - the oscillatory features are small at this wavelength, it should be kept in mind that the onset of the SE occurs with a delay of ∼70 fs (Figure 4B), reflecting coherent nuclear motion out of the Franck-Condon region. This effect complicates the analysis of rise phases occurring on a similar time scale, as discussed in section 3.2.4. The fact that the observed apparent rise kinetics of ∼180 fs upon excitation at 770 nm is significantly slower a posteriori justifies the simpler approach of fitting with an exponential function in this case.

In ref 21 it was also ∼1 nm (as mentioned) for the kinetics at single wavelengths, but (as remarked only after the appearance of the paper) somewhat more elevated for the spectra, which were recorded using a different detection setup. The difference in spectral resolution is clearly apparent when comparing the ground-state spectra in the 800 nm region.
