Photodissociation of Dimethylnitramine at 248 nm

Article abstract of DOI:10.1021/j100160a018

The production of OH A²Σ⁺, OH X²Π_i, NO2 A²B₂, NO21 X²A₁, and NO X²Π following dimethylnitramine (DMNA) photolysis at 248 nm has been investigated by using laser-induced fluorescence and emission spectroscopies.NO2 A²B₂, NO2 X²A₁, and OH X2Π_i are formed via monophotonic, unimolecular pathways.The quantum yields for NO2 X²A₁ and OH X²Π_i production are estimated to be 0.15 and 0.004, respectively.The unimolecular production of NO X²Π (ν''=0) was not observed, implying its quantum yield is <0.001.OH A²Σ⁺ is formed via a two- photon, unimolecular process.These results are compared with previous studies investigating the thermal and photochemical decomposition of DMNA.
