The analysis of IR spectra of free OH groups in strongly dealuminated zeolite HY (Si/Al 100) restoring on desorption of ammonia or pyridine provides spectroscopic evidence for the homogeneity of SiO 1 HAl groups. The same conclusion is obtained by analysis of the IR spectra of OH and OD groups inter
