N2 - ESR spectra of the radical species derived from 60Co γ-ray irradiation of 1,3,5-cycloheptatriene (1,3,5-CYT) and 1,3-cycloheptadiene (1,3-CYD) in halocarbon matrices have been studied in the temperature range 70-103 K. Ring inversion across the molecular plane occurs in the radical cation 1,3,5-CYT+{radical dot} in CCl3CF3, the activation energy being 1.7 kcal/mol. Above 90 K, 1,3,5-CYT+{radical dot} is deprotonated thermally in CCl2FCClF2. No dynamical effect has been observed for 1,3-CYD+{radical dot}.
