Abstract in another language
Oxygen-17 spin relaxation and stimulated-echo experiments are carried out to study temperature-dependent reorientational time scales in potassium permanganate. From an analysis of the present data, an energy barrier of 0.35 eV is found. This activation energy is much larger than the one reported previously (Jakobsen et al. Quantitative Dynamics and Structure for Crystalline Cs2WO4 and KMnO4 Determined from High-Field O-17 Variable-Temperature MAS NMR Experiments, J. Phys. Chem. C 2014, 118, 20639-20646), but it is on the order of magnitude expected from observations for the dynamics of other tetraoxoanions in ionic crystals. The various contributions to the measured spin relaxation times and details regarding the two-time correlation functions for KMnO4 are discussed.
