We have observed quadricyclane and norbomadiene radical cations in different pentasil type zeolites by EPR spectroscopy after 4 K in situ electron beam irradiation of samples in the EPR spectrometer. We report the first evidence for matrix isolation of the quadricyclane radical cation. It is stable
