    • Our experimental estimation has to be compared with the present computational results, which indicate a gap of 3.47 eV for HQ, 0.79 eV for SQ, and 1.08 eV for IQ from Figure 3, These values are comparable, with those collected by Powell et al.,4 where a HOMO-LUMO gap in the 1.3-2.02 eV range is reported for the indolequinone, 0.8-1.50 eV for semiquinone, and 3.4-4.53 eV for the hydroquinone

    • To exclude the normal Auger emission, we focus on the resonant part of the valence band low-BE region, where the bands involved in the UV-vis optical absorption are located e.g, the A band
