✦ Synopsis

a-Alkyldibenzylketones included in cation exchanged faujasite type zeolites show photobehavior different from that in isotropic organic solvents. Rearrangement and disproportionation which do not contribute in solution are the major processes within the cavities of faujasites.

Cation size plays a major role in controlling the pathway pursued by the primary and the secondary radical pair.
