title: Kinetic and Theoretical Study of the Nitrate (NO3) Radical Gas Phase Reactions with N-Nitrosodimethylamine and N-Nitrosodiethylamine.
abstract: The reaction rates of (CH3)2NNO and (CH3CH2)2NNO with NO3 radicals were determined relative to formaldehyde (CH2O) and ethene (CH2CH2) at 298 ± 2 K and 1013 ± 10 hPa in purified air by long path FTIR spectroscopy. The reactions are too slow to be of importance at atmospheric conditions: kNO3+(CH3)2NNO = (1.47 ± 0.23) × 10(-16) and kNO3+(CH3CH2)2NNO = (5.1 ± 0.4) × 10(-16) cm(3) molecule(-1) s(-1) (1σ error limits). Theoretical calculations, based on CCSD(T*)-F12a/aug-cc-pVTZ//M06-2X/aug-cc-pVTZ results, predict the corresponding imines as the sole primary products in nitrosamine reactions with NO3 and OH radicals.
