摘要：

Products O-3, N, NO, NO2, N2O, c-(NO)(2), and excited states of O-2 were detected after the photolysis of solid O-2 in icy N-2 near 4 K with radiation at 200 nm. The temporal profiles of these products enable the derivation of a mechanism for the photochemical reactions in this system: dissociation of O-2 first-generated (OP)-P-3 that reacted with nearby N-2 to yield N2O. Other products resulted from the secondary photolysis of N2O and the reactions of O with N2O. The reaction of O with O-2 to form O-3 was impeded by the small concentration of the latter, which requires substantial migration through the N-2 lattice. However, sufficient O-3 was eventually formed to enable detection either directly from O coming from O-2 or indirectly through N2O. These results enhance our understanding of the evolution of the transformation of oxygen and nitrogen in irradiated ices and have possible astrophysical applications.
