Abstract
Recently, there has been increased interest in using <sup>2</sup>H MAS NMR spectroscopy as an alternative to 'static' quadrupolar-echo NMR for studying dynamics in solids. Here we show that the phenomenon of enhanced spin diffusion as a result of <i>n</i> = 0 rotational resonance can lead to observation of a common spin-lattice (<i>T</i><sub>1</sub>) relaxation time for all deuterons. Thus, if rapidly relaxing groups are present, such as -CD<sub>3</sub> or -<font size="3">ND<sub>3</sub><sup>+</sup></font> groups, then even highly immobile deuterons can exhibit <i>T</i><sub>1</sub> relaxation times of ∼1s under MAS conditions, greatly facilitating data acquisition.
