The authors propose a novel mechanism for isotopic exchange between CO{sub 2} and O{sub 3} via O({sup 1}D) + CO{sub 2} {yields} CO{sub 3} followed by CO{sub 3}* {yields} CO{sub 2} + O({sup 3}P). A one-dimensional model calculation shows that this mechanism can account for the enrichment in {sup 18}O in the stratospheric CO{sub 2} observed by Gamo et al. (1989), using the heavy O{sub 3} profile observed by Mauersberger (1981). The implications of this mechanism for other stratospheric species and as a source of isotopically heavy CO{sub 2} in the troposphere are briefly discussed.
