APPLICATIONS OF HIGH-RESOLUTION SOLID-STATE NUCLEAR MAGNETIC-RESONANCE SPECTROSCOPY TO SURFACE STUDIES

This review focuses on surface characterization using the techniques developed for solid state magic-angle NMR where the observe nucleus is chosen to suit the surface system. The NMR studies of surfaces carried out to date can be divided primarily into 2 areas: the characterization of chemically modified silica surfaces and the study of the nature of molecular adsorption on catalytic surfaces. The solid state NMR studies of these systems have demonstrated that high resolution spectra are attainable and that this method of characterization, with its capabilities and relative ease of interpretation, is a valid and useful one.
