A comprehensive nuclear magnetic resonance (NMR) study has been carried out for hydrogen dynamics in a sol-gel-prepared ZnO system. The temperature-dependent linewidth and chemical shift measurements sensitively reflected the proton motions and changes in the local environment. Besides, two types of interstitial proton (1-I ) motions were distinguished from the spin-spin relaxation time measurements, one of them with an activation energy of 016 eV and the other with that of 033 eV depending on the temperature ranges.
