• An apparatus was constructed for ESR measurements during electron irradiation, and the behavior of transient radicals in the plastic crystals of cyclohexane (CyH) and 2,2,3,3-tetramethylbutane (TMB) was investigated. It was found from the experiment that cyclohexyl radical produced by irradiation of CyH decays with a rate constant of 2×10<SUP>−8</SUP> exp (−7.9 kcal/<I>RT</I>) cm<SUP>3</SUP>/s. The rate constant is in good agreement with the results reported by Buben <I>et al</I>. On the other hand, radicals formed in irradiated TMB were assigned to be<BR>(<U>Remark: Graphics omitted.</U>)<BR>from the present results. It was shown from the results that the assignment made by Marx <I>et al</I>. before should be corrected to some extent. In the plastic crystals of CyH and TMB, it was suggested that the decay reactions of the observed radicals are controlled by the diffusional migration of the radicals. The analysis of radiolytic products of TMB was also made, and the results were compared with the results of ESR observation.
