Abstract

This review presents a self-contained summary of the experimental methods necessary to perform a low temperature solid-state NMR experiment. Specific references are made for Zn²? and Mg²?. However, this is not a comprehensive review of the NMR literature of these nuclides. As the review is concerned with solid-state NMR spectroscopy of quadrupolar nuclides, we limit the discussions to odd-half-integral spin systems, i.e. 3/2, 5/2, 7/2, and 9/2 spins. The reason for the limitation is due to the “relative ease” of observing the central transition, which is common to all of these nuclides. The review is divided into two major sections; the first dealing with experimental methods, e.g. use of low temperature, magnetization transfer, spin echo methods, and questions dealing with nonspecific binding. Following those discussions we turn to the introduction of structure into the experiment, i.e. the use triple resonance experiments to selectively introduce dipolar interactions and the use of molecular theory.
