Comparison of SAKs in different spectral regions and of transient vibrational spectra.
(a) A comparison of the SAKs obtained from SVD analyses of the visible region and mid-IR region (7352 to 9447 nm). (b) An expanded view of the vibrational spectral region of Fig. 4d. For clarity, the free electron absorption envelope in the form of λ2 has been subtracted from SAS1 and the plots are vertically displaced. The area decay for the broadened vibrational bands (blue circles) is also plotted in (a) for comparison with the SAKs.
