ABSTRACT
Solid-stateNMRhas long been used by physicists to study awide range of problems such as superconductivity, magnetism, the electronic properties of metals and semiconductors, ionic motion etc. The early experiments mostly used ‘wide line’ NMR where high resolution was not required but with the development of the technique, particularly the improvements in resolution and sensitivity brought about by magic angle spinning (B1.12.4.3), and decoupling and cross polarization (B1.12.4.4), solid-state NMR has become much more widely used throughout the physical and, most recently, biological sciences. Although organic polymers were the first major widespread application of high-resolution solid-state NMR, it has found application to many other types of materials, from inorganics such as aluminosilicate microporous materials, minerals and glasses to biomembranes. Solid-state NMR has become increasing multinuclear and the utility of the technique is evidenced by the steady and continued increase in papers that use the technique to characterize materials. There is no doubt that the solid-state NMR spectrometer has become a central piece of equipment in the modern materials physics and chemistry laboratories.
