H 2'AI and %i solid-state NMR was used to determine the geometry of the Brsnsted acid site in zeolites. The mean distance between acidic protons in bridging hydroxyl groups and the nearest framework Al atom is 2.38 ? 0.04 8, in zeolite H-Y and 2.48 2 0.04 A in H-ZSM-5. The quadrupole frequency of fr
