Study of the atmospheric reaction processes of iodide molecules

本研究利用时间分辨光腔衰荡光谱技术测量了硝酸根（NO_3）与碘原子反应的速率常数，研究了反应性碘化合物和大气碘气溶胶的形成过程。由测定的速率常数可知，NO_3自由基与I原子的反应对大气中活性碘化合物和大气碘气溶胶的生成过程可能没有太大的影响。

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.
