“…Haloalkane radicals such as -CC13 are believed to react efficiently with oxygen to form peroxy radicals. 18 The monomer cation is not considered to be removed by oxygen, since in alkane-BuCl matrices the presence of oxygen assisted dimer-cation formation.19 The removal of aromatic cation radicals by oxygen has not been reported as far as the authors know. Therefore, R is identified with •CF2CF2Br.…”

Naphthalene solutions in a Freon mixture consisting of CFC13 and CF2BrCF2Br were y irradiated at 77 K and then warmed to 83.7 K. Warming produced an intermediate having a characteristic absorption band at 0.76 Atm on the change of a naphthalene cation to a dimer cation. Analysis of the effects of both naphthalene concentration and dose led to a conclusion that the intermediate is a complex of the naphthalene cation with •CF2CF2Br. Another new species absorbing strongly near 1.16 pm was formed from the dimer cation upon warming. This band was assigned to a tetramer dication, S42+-2Br-. Extinction coefficients of the new species as well as those of the naphthalene cation and dimer cation were determined.
