NMR of Physisorbed 129Xe Used as a Probe to Investigate Molecular Sieves

Xenon is an inert gas with a very large electron environment that makes it sensitive to any interaction, even physical. In the case of 129Xe isotope (spin 1/2), the resulting electronic perturbation is directly transmitted to the nucleus and, therefore, affects the nuclear magnetic resonance chemical shift. In this chapter, we report some applications of this technique in both fundamental and applied research in the field of microporous and mesoporous solids.
