Abstract
The 532 nm multiphoton dissociation of NO2 has been investigated, following the work of Matsumi et al. [Laser Chem. 1, 113 (1983)], which demonstrated that highly vibrationally excited O2 (v≤25) is a product. We have shown that O2(v) is generated in a secondary reaction, possibly through the interaction between primary O(1S) and the parent molecule. Competitive quenching experiments with N2 indicate that O(1D) is not involved in O2(v=24) production. Primary NO(v) has been detected by one‐ and two‐photon excitation, with v≤7. Its source is probably 532 nm two‐photon dissociation of NO2. The generation of O(1S) requires absorption of four 532 nm photons by NO2.Keywords
