The MIF in Ozone Formation

Understanding the mass-independent isotope fractionation effect for ozone in the laboratory [5] and stratosphere [9] poses interesting challenges. These chal-

We first summarize a theory applied to the MIF effect in ozone formation [12-15]. The theory of the MIF in ozone formation involves several concepts, some of which are well established in the literature by many studies on the rates of unimolecular dissociation and bimolecular recombination reactions [34-39]. The main features of this analysis of the MIF in ozone formation are summarized below.
