Overview of the depletion-corrected excited-state photoelectron spectrum and its time dependence. a Dataset from Fig. 3b) after depletion correction (see text). The excitation was determined to be 1.3%. b Mean difference spectrum outside of the temporal overlap (cf. Fig. 3d). XUV only spectra of both NO₂ and NO are overlayed to indicate the origin of individual contributions. The NO spectra were acquired with a different magnetic-bottle spectrometer⁶¹. c Same data with the region between 7 and 15 eV magnified and superimposed calculated spectra. The binding energy range matches the energies where the cationic states included in our model, suffice to describe the system. The corresponding energy domains are labeled by bars of the same colors in a. d The four selected bands described in the text, each renormalized to a peak amplitude of 1. e Mean variation of each band as a function of time delay and f The center of gravity calculated for two selected bands. The color code of the bands in d–f is identical
