Abstract
Rotational echo double resonance (REDOR) is used to analyze ionic motion in tetrahydroxoborate sodalite, which can be regarded as a model system for rotor phases. The motional averaging of 11B−1H and 23Na−11B dipole interactions probes both the reorientation of the tetrahydroxoborate anions and the sodium motion, respectively. To this end, REDOR data from multiple-spin systems with quadrupolar nuclei have to be analyzed quantitatively, and the underlying theoretical model is presented. The results show that simple 23Na NMR line narrowing analysis can lead to misleading conclusions, and the REDOR method is a valuable tool to investigate local motion in ionic systems.
