Abstract

The dynamics of xenon motion between the α-cages of zeolite NaA have been studied using ¹²⁹Xe nuclear magnetic resonance (NMR) inversion-recovery experiments. The apparent spin-lattice relaxation times suggest that the rate of intercage hopping decreases with loading. An upper limit for the intracrystalline diffusion of xenon in NaA is also calculated and is consistent with estimates made from other techniques.
