Comparison between our calculated spectra with those obtained in the experiment (Hudson et al. 2017). The results of Hudson et al. (2017) have been digitally extracted using https://apps.automeris.io/wpd. Upper panel: the mid-IR region. Lower panel: the near-IR region. For the sake of better visualization, we scaled down the Y-axis of our calculated values in (a) and (b). Our calculated wavenumber in the X-axis of (b) is scaled by 0.9728 to have better agreement.
