Spectroscopy of Solids

Abstract

Driven both by technological and methodological advances, major progress has been made over the past decade in improving the quality of 1H NMR spectra in the solid state. Traditionally high-resolution solid-state 1H NMR involved specialised and often challenging techniques, but the advent of fast magic-angle spinning (MAS) probes, higher magnetic fields, and RF decoupling schemes that complemented, rather than competed with, MAS has considerably simplified the task of obtaining useful 1H spectra from solids. After introducing the factors that determine resolution in 1H NMR and the approaches used to narrow 1H linewidths, the relevant literature over the past decade is reviewed. The final section presents a selection of applications, highlighting the different areas to which resolved 1H NMR spectra can now be applied.
