Studying magic angle spinning

Abstract Membrane proteins represent an important and challenging frontier in structural biology they mediate fundamental and medically important processes but are challenging targets for structure/ function studies. Magic angle spinning solid-state NMR methods for structure determination of proteins have developed rapidly in... 

Solid-state Alnmr spectroscopy has been much used in recent years to study the composition and structure of aluminisilcates (pp. 351 -9) and other crystalline or amorphous Al compounds. The technique of magic angle spinning (MAS) must be used in such cases. ...

Although limited by sensitivity, chemical reaction monitoring via less sensitive nuclei (such as 13C) has also been reported. In 1987 Albert et al. monitored the electrochemical reaction of 2,4,6-tri-t-butylphenol by continuous flow 13C NMR [4]. More recently, Hunger and Horvath studied the conversion of vapor propan-2-ol (13C labeled) on zeolites using 1H and 13C in situ magic angle spinning (MAS) NMR spectroscopy under continuous-flow conditions [15]. 

In this review we shall emphasize some of the unique features of HREM and, in so doing, illustrate how, in association with one or other of the additional techniques mentioned above, or in association with separate studies (e.g. magic-angle-spinning solid-state NMR), HREM has clarified several new, or hitherto enigmatic, features of the chemistry of inorganic solids. In particular we discuss, how ...
