## Abstract

Five minimum energy structures have been identified for dichlorine hexoxide and ab initio calculations have been performed on these isomers at the 6-31G* and MP2/6-31G* levels. Among the five structures, the oxygen-bridged structure and a symmetrical dimer containing a C1-C1 bond were found to be stable. Normal mode analysis has been carded out on the stable conformers. The relative strength of the $O_3C1-O$ and $O-C10_2$ bonds of the oxygen-bridged structure is discussed on the basis of their vibrational frequencies. In addition, the paper focuses attention on the great importance of the reaction $2OC10 + 20_3\rightarrow C1_20_6+20_2$. The implications of these results to the chemistry of stratospheric ozone depletion are delineated.
