Infrared spectroscopic evidence for the structural OH groups of spinel alumina modifications

In the structure of spinel aluminas (γ, η, δ etc.), treated at moderate temperatures, a certain part of cation vacancies are always hydrated. Protons trapped in the octahedral and tetrahedral vacancies give rise to wide bands at about 3500 and 3300 cm −1, respectively. These bands are not affected b...
