✦ Synopsis

Continuing recent progress in the design of magic angle spinning MAS equipment now allows spinning frequencies of up to 35 kHz in commercial MAS probes. Such high frequencies make MAS an important tool for the manipulation of strong dipolar couplings, in particular when supplemented by suitable pulse techniques. This article describes convenient and simple strategies for designing techniques that are suited to application under such conditions. The strategies are then applied to widely used pulse techniques for line narrowing, recoupling of spin interactions, and multiple-quantum NMR spectroscopy. Representative results illustrate the usefulness of the techniques.

The utility of gradient selection in MAS spectroscopy of dipolar solids is explored in two examples. In the first, rotor-synchronized gradients of appropriate strength and duration are applied to select 1H double-quantum coherences. The resulting DQ MAS spectrum of adamantane is compared with that a
