The temperature dependence of the line-shape of 1H MAS NMR spectra of H-mordenite and H-MCM-22 was examined. Upon raising the temperature of measurements stepwise from 298 to 503 K, the line-width of 1H MAS NMR of acidic protons in H-mordenite with SiO 2 /Al 2 O 3 ratio of 106 increased, went throug
