Distance Measurements to Metal Ions and Other Quadrupolar Spins by Magic Angle Spinning Solid State NMR

Abstract

AbstractThe characterization of metal sites in many types of materials is essential for understanding many aspects of chemistry and biochemistry, such as catalysis, enzymatic activity, and coordination. Of the many approaches to study such sites, this review deals with the utilization of dipolar recoupling in the context of magic angle spinning solid state NMR for qualitative and, in particular, quantitative distance measurements between metals and other quadrupolar nuclei to their surrounding environment. It will focus on the development of techniques, on their applicability towards experimental realizations, on key applications to materials and biological systems, and on current challenges and limitations.
