The broadenings observed in "C MAS NMR spectra, which depend on the sample-spinning speed, were studied, using polycrystalline adamantane. Not only was a monotonic increase of the linewidths with the increase of the spinning frequency observed, but also a novel resonant feature was found. The phenom
## Abstract We here report on the influence of heteronuclear dipolar decoupling on the ^27^Al 3QMAS, 5QMAS, and the doubleโquantum filterโsatelliteโtransition magicโangle spinning (DQFโSTMAS) spectra of a strongly dipolarโcoupled system, gibbsite. The requirements for heteronuclear dipolar decoupli
For compounds giving "crowded" 1-dimensional magic-anglespinning spectra, information about the local atomic environment in the form of the chemical shift anisotropy (CSA) is sacrificed for high resolution of the less informative isotropic chemical shift. Magic-angle-turning (MAT) NMR pulse sequence
