Photoelectron spectra of dissociated and highly-excited, but still bound NO2 molecules. a The wavelength-dependent absorption spectrum of NO2 (black)60 with the individual dissociation thresholds for vibrationally cold NO262, 63, together with two excitation spectra—one dominantly above (blue) and one dominantly below (red) the dissociation threshold. b, c Depletion compensated relative difference spectra for those two excitation spectra. The excitation fraction in both data sets (b, c) is about 0.9%. d, e Mean depletion -compensated relative difference for both spectra integrated over the delay range of 3.5 to 4.5 ps. In both cases the XUV-only spectra of NO2 and NO are overlayed (see text). The NO spectra were acquired with a different magnetic-bottle spectrometer61. The photoelectron spectra predicted by our wave-packet calculations are shown as well
