ChemInform Abstract: Recent Progress in Solid State NMR

Abstract

Publisher Summary This article reviews the progress of solid-state nuclear magnetic resonance (NMR). It emphasizes on the methodological developments. The applications of the technical advances, particularly those that are significant to chemistry, biochemistry, biology, and materials science have been discussed. Higher magnetic fields, more intense decoupling power, higher spinning rates, more robust pulse sequences, and novel designs of RF coils remain the routes pursued in achieving better solid-state NMR spectra. These advances, mainly in hardware, along with developments of pulse sequences, have tremendous potential in virtually every aspect of solid-state NMR and nuclear magnetic resonance imaging. Each of these is covered in the chapter. It discusses the theoretical and computational progress in solid-state NMR, which includes calculations of the lineshapes and dynamic processes based on density matrix theory or computations of the interaction parameters based on quantum mechanics. The chapter is also devoted to progresses in the efficient decoupling of dipolar interactions in solid samples, which is another method for obtaining high-resolution NMR spectra. It summarizes recently proposed recoupling schemes and reviews various types of correlation spectroscopy. Developments in cross-polarization and spin diffusion/ exchange are reviewed and the main achievements in solid NMR imaging have also been summarized.
