Applications of magnetic resonance to the study of radiolysis are illustrated. The products of radiolytically produced radicals exhibit CIDNP when examined, seconds after their creation, by NMR. Irradiation with a pulsed electron beam (3 MeV) was carried out in variable magnetic fields and the irradiated solutions were transferred to the NMR sample tube using a fast flow system. Aqueous solutions of methanol, iodomethane, ethylene glycol, acetate, and chloroacetate were studied. In these systems CIDNP in numerous products and starting materials can be observed. The ''primary radicals'' of radiolysis e/sub aq//sup -/ and H play a significant role in the polarization pathways. Applicability of the radical pair model of CIDNP to radiation chemistry is illustrated.
