Popis:	The pulsed field gradient NMR technique is applied to study water diffusivity in natural chabazite. Information about diffusion anisotropy is deduced from both single-crystallite measurements and analysing the shape of the NMR spin–echo attenuation. With both methods the diffusivity has been found to be orientation-dependent with a ratio between the maximum and minimum diffusivity being of the order of 2.
