Broad-line 'H NMR and 'H MAS NMR were used to determine the geometry of the Bransted acidic sites in zeolites H-ZSM-5. The signals obtained correspond to bridging hydroxyl groups in Si-OH-Al arrangements with an H-Al distance of 0.246-0.252 nm. The concentration of hypothetical SiOHSi groups must be
