| heal.abstract | In this work, we studied the photooxidation of acetylene throught the glyoxal creation channel in the spectral region 280 − 325 nm. A ns multiphoton ionization study in this region revealed 2 major lines attributed to the partially dissociating (Herzberg type II pre-dissociation) Valence state ˜C ′1Ag with lifetime of around 1 ps. The impact of this state to the phootoxidation mechanism of acetylene is considered negligible compared to the impact of the pre-dissociative Rydberg states ˜C1Πu and 3p1Πg (with lifetime of around 50 fs) although absent in typical ionization studies. The photooxidation of acetylene is believed to occur in the early stages of the fragmentation process of the parent molecule after excitation to the aforesaid pre-dissociating Rydberg states. The creation of C2H radicals seems to initiate the glyoxal production (the more the dissociating channel produces C2H radicals, the more the reactivity gets maximized). The reaction is supposed to proceed via a fourmembered ring re-arrangement of the C2H radical with the molecular Oxygen (during the pre-dissociation process) in the molecular skeleton and with the addition of a free Hydrogen, glyoxal is created. | en |
