Reactions of H atoms produced by electron irradiation of benzene in solid xenon: IR spectrum of cylohexadienyl radical and possible involvement of HXeC6H5

Irradiation of benzene in a xenon matrix at 16 K leads to H atoms and phenyl radicals, and annealing at 45 K results in formation of HXeH and cyclohexadienyl radical. A computationally stable molecule HXeC6H5 is either not formed or not stabilized under the experimental conditions used.
