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
## ลฝ . The diffusivities of long n-alkanes in ZSM-5 have been measured by quasi-elastic neutron scattering QENS . Self-diffusion coefficients and activation energies for chains up to C have been obtained. Reasonable agreement is 14 observed with single-crystal membrane experiments, except for C ,
