Irradiation of gaseous diethylnitramine with infrared radiation from a pulsed CO2 laser under collision-free and collisional conditions resulted in the formation of diethylnitrosamine as the main product along with nitrogen dioxide, nitric oxide, formaldoxime, and diethyl nitroxide.Scavenging experiments with Cl2, NO, and (CD3)2NNO2 molecules have shown that the primary channel of unimolecular dissociation of diethylnitramine molecules is the scission of the N-NO2 bond, with a steady-state rate constant of 10^{5.2 +/- 0.1}(I/MW cm^-2) s^-1 for laser intensities in the range 3-15 MW cm^-2 at an irradiation frequency of 1075.9 cm^-1.A qualitative analysis of the chemical mechanism leading to the formation of final products as well as the importance of the diethylamino radical oxidation reactions is presented.
