Abstract

The products of the Cl + OClO reaction have been studied using submillimeter wave spectroscopy. The ClO initially formed reacts with the excess OClO to give $Cl_{2}O_{3}$. The products of the ClO self reaction are not apparent under the present experimental conditions. The spectra of the 35-35, 37-35, 35-37, and 37-37 species of $Cl_{2}O_{3}$ have been assigned and fitted. The rotational constants and chlorine substitution coordinates are consistent with a classical chlorine chlorate structure. The experimental apparatus will be described. The spectrum, molecular parameters and the role of $Cl_{2}O_{3}$ as a potential reservoir for active chlorine in the polar stratosphere will be discussed.
