Figure 2.
Q modes (right panels) and corresponding 2D wavelet power spectra (left panels). The color scale states for the intensity are in arbitrary units: a) a ring deformation mode combined with hydrogens out-of-plane motion, with an AIMD frequency at about 930 cm–1, an exp. value of 952 cm–1, an exp. rise time of 140 fs, and a decay time of 600 fs (from ref (47)) and b) a combination of ring wagging and breathing mode, with an AIMD frequency of 620 cm–1, an exp. value of 630 cm–1, and an exp. rise time of 300 fs.
