Isotopic exchange between carbon dioxide and ozone via O(1D) in the stratosphereA novel mechanism for isotropic exchange between CO2 and O3 via O(1D) + CO2 - CO3(asterisk) followed by CO3(asterisk) - CO2 + O(3P). A one-dimensional model calculation shows that this mechanism can account for the enrichment in O-18 in the stratospheric CO2 observed by Gamo et al. (1989), using the heavy O3 profile observed by Mauersberger (1981). The implications of this mechanism for other stratospheric species and as a source of isotopically heavy CO2 in the troposphere are briefly discussed.
