The Brønsted acidity of H-mordenite (H-MOR) and H-b with similar Si/Al ratios has been characterized by conventional multinuclear solid-state NMR. 1 H/ 27 Al TRAPDOR NMR showed the presence of at least two different types of Brønsted acid sites in H-b. On the other hand, only a single 1 H resonance
