Summary:The location of charge-balancing sodium cations plays an important role in determining the adsorption and catalytic properties of zeolites.Solid-state 23Na nuclear magnetic resonance （NMR） can provide information about the distribution and chemical surroundings of sodium cations in zeolites.A number of papers have been published using various 23Na NMR techniques to investigate the distribution of sodium cations and their interactions with water molecules in hydrated zeolite A, zeolite Y and sodalites.In addition, Challoner et al. have studied the motion of sodium
