✦ Synopsis
Xenon is an inert gas whose large polarizability makes it very sensitive to electronic perturbation which is directly transmitted to the nucleus and therefore markedly affects the chemical shift. This overview, which is not exhaustive, presents some characteristic examples of the use of 129 Xe NMR to study micro and mesoporous solids.

We report a systematic study of xenon gas diffusion NMR in simple model porous media, random packs of mono-sized glass beads, and focus on three specific areas peculiar to gas-phase diffusion. These topics are: (i) diffusion of spins on the order of the pore dimensions during the application of the
