Simplified cluster models representing catio binding sites in a zeolite ferrierite structure have been optimized with a series of divalent Mg(2), Mn(2), Co(2), Ni(2) and monovalent Na(1), Cu(1), Ag(1) metal cations. A sound correlatin has been found between the extent of perturbation and the measured infrared vibrational wavenumbers of the shifted T-O-T antisymmetric skeletal vibrations, appearing in the 1020-780 cm-1 region of the FTIR spectra of ferrierite exchanged with metal cations.
