    • -2 was determined, which is similar in value to that obtained by in situ spectroscopy. This may serve as a cross-check to ensure the reliability of our present estimation.

    • note
    • Repetition rates of 1 kHz and 100 Hz yield basically similar results for the extinction spectral changes. For instance, a I A vs fluence plot for 100 Hz is given in the Supporting Information, Figure S6, showing a threshold for the fragmentation similar to that observed in Figure 3 but with decreased I A values because of a reduced number of laser shots.

    • Technically, the best probe wavelength was slightly adjusted at ̃490 nm to obtain the lowest net absorption signal due to the electron-phonon dynamics.
