Chlorine dioxide

Other Names

OClO, ClO2


Chlorine dixide (OClO), a major ozone-destroying radical, is a higly reactive gas species.
OClO plays an important role in the chemistry of polar stratospheric ozone depletion, as it is a product of the reaction of ClO with BrO. Its detection in the antarctic ozone hole was one of the key discoveries that pointed to chlorine chemistry being the major cause of polar stratospheric mountain-wave cloud depletion.
