Abstract Infrared absorption spectra (400–4000 cm−1) were measured on dehydrated and partially dehydrated powder of the zeolite harmotome Ba2[(AlO2)4(SiO2)12]·12H2O. Whereas the disappearance of the bending mode at ∼1640 cm−1 proved the absence of water molecules after dehydration, the O-H stretching mode at 3200 cm−1 showed the presence of hydroxyl groups. The vibrational modes of the framework are only slightly influenced by dehydration.
