摘要

The course of the reaction of electronically and vibronically excited metastable O-2(+)((4)Pi(u,) nu') ions with O-2, known to produce O-3(+), was examined by the joint application of computational and mass spectrometric methods. The results show that the reaction does not proceed by a direct mechanism and that it involves instead the intermediacy of the [O-2(+)((4)Pi(u))...O-2] and [O-3(+)((4)A(2))...O] complexes, both theoretically characterized, and the latter one positively identified by structurally diagnostic mass spectrometric techniques. The reaction is a potential source of stratospheric ozone, in that O-3(+) ions are known to undergo efficient charge exchange with oxygen to yield neutral O-3. [References: 42]
