For Ada-CN + , three bands are observed in the energy range up to 7 eV (Fig. ), while the vibrationally resolved spectrum in Fig. displays two bands. The first two bands (of the broaden spectrum calculated at the initial geometries) bear similarity to the experimental spectrum as well as to the VG spectrum presented above (Fig. ). Two excitation energy windows were considered in the case of Ada-CN + , eV and eV, corresponding to the first and the second bands, respectively.
