NO3自由基的形成,观察到以下光解的CH2I2 + O2系统在248 nm下的环境大气边界层条件下(10760托和297 K)在NO2的存在下。Criegee中间体(Cl)CH2OO被认为是NO3产生的原因。这种反应,以提高在大气中的NO3生产率的潜力进行了讨论。
Formation of the NO3 radical was observed following photolysis of the CH2I2 + O2 system at 248 nm under ambient atmospheric boundary layer conditions (∼760 Torr and 297 K) in the presence of NO2. The Criegee intermediate (CI) CH2OO is believed to be responsible for the NO3 production. The potential of such reactions to enhance the rate of NO3 production in the atmosphere is discussed.
