| Abstract: | Crystals of CsH(SO4)0.76(SeO4)0.24 formulation were studied by 1H NMR spectroscopy. The 1H line-shape, the T1 and T2 relaxation times were determined as a function of temperature. The activation energies deduced from the temperature dependence of relaxation times were compared with the activation energy issued from conductivity measurements. The results obtained are discussed and supported by the Ngai model. |
