<I>Cis</I>-to-<I>trans</I> one way isomerization of stilbene in the first case catalyzed by proton, and then, secondly through electron transfer, occurred in acidic zaolites without light, suggesting that dimer cation radicals with charge transfer interaction between <I>trans</I>-stillbene and its cation radical may be formed in H-ZSM-5, whereas 1,4-dimer cation radicals of stilbene may be produced in H-mordenite.
