Received Date: 4 December 1990

Fe³⁺ substituted ZSM-5 zeolite was studied using EPR and ²⁷Al, ²⁹Si MAS-NMR spectroscopy. The results showed that the synthe-sized sample has the typical ZSM-5 structure with Fe³⁺ ionsincorporated in tetrahedric sites in the zeolite framework and there are some para-magnetic centers in the samples.
