Abstract
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.
摘要
在大气边界层条件（~760 托和 297 K）下，在存在 NO2 的情况下，用 248nm 的光解 CH2I2 + O2 体系时观察到了 NO3 自由基的形成。人们认为 Criegee 中间体（CI）CH2OO 是产生 NO3 的原因。讨论了这种反应增强大气中 NO3 生成速率的潜力。
