It has recently been suggested that isotope exchange between excited bimolecular oxygen and ozone may be partially responsible for the enrichments in stratospheric heavy ozone. To begin evaluating this possibility we have investigated the reaction ^(18)O_2(^1Δ)+^(16)O_3→(labeled ozone products) using a fast-flow reactor and molecular beam mass spectrometry. No reaction was observed, implying that the rate coefficient must be less than 5 × 10^(−16) cm^3/s molecule at 300 K, roughly two orders of magnitude smaller than is required to account for the atmospheric anomalies.
