摘要：

The production of OH A2-SIGMA+, OH X2-PI(i), NO2 A2B2, NO2 X2A1, and NO X2-PI following dimethylnitramine (DMNA) photolysis at 248 nm has been investigated by using laser-induced fluorescence and emission spectroscopies. NO2 A2B2, NO2 X2A1, and OH X2-PI(i) are formed via monophotonic, unimolecular pathways. The quantum yields for NO2 X2A1 and OH X2-PI(i), production are estimated to be 0.15 and 0.004, respectively. The unimolecular production of NO X2-PI (upsilon" = 0) was not observed, implying its quantum yield is < 0.001. OH A2-SIGMA+ is formed via a two-photon, unimolecular process. These results are compared with previous studies investigating the thermal and photochemical decomposition of DMNA.
