Development and Application of In Situ High-Temperature, High-Pressure Magic Angle Spinning NMR
Solid-state NMR has served as an important tool for investigating chemical systems, not only to better understand the structure of materials, but also to probe the interactions that occur between two or more constituents. Disparities between realistic chemical environments and those experienced during spectroscopic measurements have challenged a firm understanding of these systems. To address this concern, novel methods of conducting NMR spectroscopy under conditions of high pressure and high temperature have been developed to simulate these harsh conditions. Herein, the advancement of this technology is described by detailing the design iterations as the methods have matured to their present state. Several applications from the fields of geochemistry, catalysis, and materials science are recounted that demonstrate the capabilities and usefulness of high-temperature, high-pressure MAS NMR across diverse facets of scientific study.
