HZSM-5 zeolites and H mordenite were studied using diffuse reflectance i.r. spectroscopy in the region of stretching vibrations of hydroxyls. A new type of acidic OH groups was detected that represents a bridged hydroxyl forming a strained intramolecular hydrogen bond with a neighboring oxygen atom. Properties of the new type of hydroxyls were investigated and are discussed.
