Unimolecular reactions of a series of chemically activated cycloalkyl radicals, vibrationally excited to the region of about 45 kcalmole, were studied in the gas phase. Cyclopropylethyl, cyclobutyl, cyclopentyl, and cyclohexyl radicals were produced by H-atom addition to the appropriate olefin. Straight chain ring-opened products were observed for the first three of these radicals, while cyclopentylmethyl radical was the major product of the fourth. Critical threshold energies for these reactions have been deduced. Ring strain is discussed. Modified author abstract
