EPR studies in zeolites are reviewed in which radiolysis was used to ionize the zeolite
lattice, create reactive intermediates, spin label reaction products and to provide a window
onto chemistry and transport of adsorbates and matrix control of chemistry. The review
examines reactions of radical cations and the influence of the geometry constraints inside
the zeolite, explores how zeolite model systems can be used to learn about energy and
charge transfer in solids and illustrates the use of radiolysis and EPR for in situ
spectroscopic studies of solid-acid catalysis. The various spin probes created inside the
zeolite pores report on properties of the zeolites as well as shed light on radiolytic
