Distribution of aluminium in the framework of ZSM-5 and Beta zeolites, represented by "Al pairs" and single "Al atoms" far distant from each other, is estimated from the distribution of divalent Co ions at the individual cationic sites, as obtained from the Co(II) Vis spectra, and the changes in the concentration of OH groups and Levis sites due to Co(II) exchange, monitored by FTIR.
