Research Abstract

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.
