R.A.Shakhovoy, A.Rakhmatullin, M.Deschamps, V.Sarou-Kanian, C.Bessada, 'Nuclear magnetic resonance study of sulfate reorientations in LiNaSO4', J. Phys. Cond. Mat. 28 176003 (2016) doi:10.1088/0953-8984/28/17/176003

A nuclear megnetic resonance study of the sulfate ion reorientations in β-LiNaSO4 has been carried out. The influence of the SO4 reorientational jumps on the quadrupolar interactions of 7Li nuclei was investigated by a jump reorientational model, which has not previously been applied to sulfates. The activation energy required for the SO4 reorientations was found to be 0.19 eV. It was also revealed that the SO4 reorientational disorder should be associated with a small anomaly of a heat capacity at around 600 K, which was previously observed experimentally.
