The dynamics was investigated by trajectory surface-hopping calculations, and the core ionization energies were calculated for geometries sampled from these. The molecule was excited by a UV laser and dynamics was probed on the oxygen, nitrogen and carbon site by core electron spectroscopy. Assuming a particular model, we find that the initially excited $S_2(\\pi\\pi^*)$ state of ","authors_text":"Alberto De Fanis, Bj\\\"orn Senfftleben, Bruno Nunes Cabral Tenorio, Carlo Callegari, Caterina Vozzi, Daniel E.
