a, Schematic of the experimental set-up with both gas and solution flat-jet targets. b, Molecular-orbital diagram of the photo-excitation of pyrazine. Arrows indicate the main transition character of the valence excited states: 1B2u(ππ*), 1B3u(nπ*) and 1Au(nπ*). c,d, XAS spectra and time-averaged differential absorbances (over 150 fs) covering the water window from the carbon to nitrogen K-edges for the gas phase (c) and the solution phase (d). No energy shift in the ground-state pyrazine (static measurement) at the carbon pre-edge peak (285.3 and 285.8 eV) was observed between the solution and gas phases. The nitrogen pre-edge peak was 398.7 eV in the gas phase compared to 398.9 eV in the solution phase, so that there was an energy shift of about 0.2 eV. e,f, Enlargement of the carbon K-edge for the gas phase (e) and the solution phase (f). g,h, Enlargement of the nitrogen K-edge for the gas phase (g) and the solution phase (h).
