Abstract
The rate of ozone recombination, \({{\rm O}_2+{\rm O}+{\rm M} \rightarrow {\rm O}_3+{\rm M}}\), is strongly sensitive to the masses of the participating oxygen isotopes—the effect ultimately leading to the unconventional fractionations of ozone isotopomers in the Earth atmosphere. The mass dependence for asymmetric molecules is reconstructed, within the strong collision approximation, from the partial widths of narrow resonances of O3 and demonstrated to stem from the contributions of highly rotationally excited ozones.
