From the similarity of the recommended values and those listed in Table 4, it does not appear that there is a chain-length effect for reaction of CF3 (CF2 )x CHCl2 with hydroxyl radicals. 55 years using a variety of modeling techniques Atmospheric Perfluorinated Acid Precursors 21 (Kanakidou et al. 1995; Prather and Spivakovsky 1990; Wild et al.
2000) and x = 1 (Young et al. 2009b). Reactions of CF3 CF==CF2 in the presence of NOx gave CF3 C(O)F and C(O)F2 in approximately 100% yield when initiated by chlorine atoms or hydroxyl radicals. Similarly, CF3 CF2 C(O)F and C(O)F2 were each observed in a yield of unity from the atmospheric oxidation of CF3 CF2 CF==CF2 in the presence and absence of NOx . These products are formed through the reactions described in Hydrofluoroolefin (HFO) Mechanism Section and confirm CF3 (CF2 )x CF==CF2 as precursors of PFCAs.

The atmospheric lifetime of CF3 CHClBr can also be limited by photolysis: CF3 CHClBr + hv → products (15) This reaction has been the subject of two studies, both of which observed photolysis of CF3 CHClBr to occur slowly in the troposphere.
