{sup 129}Xe NMR spectroscopy of xenon gas adsorbed in clays and pillared clays has been used to glean information on the interlayer gallery height of clays before and after pillaring. Two clay minerals were studied, a Ca{sup 2+}-montmorillonite and Bentonite L. The NMR results indicate that the effective interlamellar spacing of the montmorillonite increased from 5.4 to 8.0 Angstroms after pillaring with aluminum polyoxohydroxy Keggin cations. These data are consistent with X-ray powder diffraction results, which show a corresponding increase in gallery height from 5.6 to 8.4 Angstroms.
