Study of the atmospheric reaction processes of iodide molecules

为了研究一种新的活性碘化合物的形成过程和最近引起人们关注的大气碘气溶胶，用时间分辨腔衰荡光谱测量了硝酸根(NO3)与I原子反应的速率常数。从测定的速率常数来看，NO_3自由基与I原子的反应可能对大气中活性碘化合物和大气碘气溶胶的形成过程没有太大影响。

In this study, to investigate a new formation process of the reactive iodine compounds and the atmospheric iodine aerosols which was recently attracted the attention, The rate constant of the reaction of nitrate radical (NO_3 radical) with I atoms was measured using time-resolved cavity ring-down spectroscopy. From the determined rate constant, it is likely that the reaction of NO_3 radical with I atom does not have a much influence on the formation process of the reactive iodine compounds and the atmospheric iodine aerosols in the atmosphere.
