Y zeolites gives Norrishtype I products in addition to the products obtained via the NorrishtypeII process, the only observed process in isotropic media. Enhancement of the type I over the typeII process is cation-dependent and especially large enhancements are obtained with Li and Na as cations. The zeolite effect is attributed to a reduction in the rate of the NorrishtypeII α-hydrogen abstraction
