The temperature dependencies of NMR spectra of 1 H, 23 Na and 27 Al nuclei in natrolite Na 2 Al 2 Si 3 O 10 2H 2 O have been studied. It has been shown that the model of the normal distribution of the activation energy may be considered as a preferable model for the diffusion of the water molecules in the natrolite. The influence of the water molecule diffusion on the NMR spectra of 23 Na and 27 Al has been discussed. It has been established that the internal mobility of aluminium and sodium ions does not occur in natrolite.
