摘要：

The phenomena of dipolar recoupling in fast-magic angle spinning (MAS) solid state NMR spectroscopy, was investigated. The analysis was based on the REDOR scheme and the related BaBa scheme for heteronuclear and homonuclear recoupling. The experiment performed on 13C at high spinning speeds showed that the proton-decoupling performance of MAS is high enough to allow for low-power RF decoupling. It was concluded that the fast-MAS NMR opens up unique opportunities to investigate the molecular structure and dynamics of solid materials.
