摘要：

High-speed MAS gives a three-fold gain in resolution of the m <-> m-1 (m = 3/2 and - 1/2) satellite transitions of I = 5/2 nuclei in polycrystalline samples compared with the conventional "central transition" spectroscopy. This is demonstrated using a standard high-field NMR spectrometer and samples of tieilite and mullite. Signals from four- and six-coordinated Al are separated completely, and rotational sidebands do not overlap. Different six- and four-coordinated Al species can be distinguished.
