Abstract The authors propose a novel mechanism for isotopic exchange between CO2 and O3 via O ((1)D) + CO2 -> CO3 followed by CO3 -> CO2 + O((3)P). A one-dimensional model calculation shows that the mechanism can account for the enrichment in 18O in the stratospheric CO23 observed by Gamo et al. (1989), using the heavy O3 profile observed by Mauersberger (1981). The implication of the mechanism for other stratospheric species and as a source of isotopically heavy CO2 in the troposphere are briefly discussed.
