Chapter 9: Probing Exchange and Diffusion in Confined Systems by ¹²⁹Xe NMR Spectroscopy

Over the last two decades, ¹²⁹Xe-gas NMR has become a well-known method to probe porous materials, as the chemical shift of the gas is highly sensitive towards its surrounding. Thus, this non-destructive technique is suitable to characterize the pore structure and the interconnectivity as well as the dynamical behavior of a fluid inside the pore space. This chapter provides an overview on the application of ¹²⁹Xe-MR for probing exchange and dynamics in porous media. Therefore, the NMR-related features and hardware requirements are discussed at first before common experimental techniques and their application examples are introduced.
