✦ Synopsis

133

The Cs and deuteron NMR measurements of the superionic transition in CsDSO showed that the mechanism of 4 protonic conductivity involves thermally-activated hopping of deuterons over well-defined lattice sites. The present 2D exchange NMR study of O-D...O deuteron interbond motion provided evidence that slow deuteron exchange between two differently oriented hydrogen bonds in the unit cell of CsDSO already takes place at room temperature, thus indicating 4 precursor effects of the superionic transition far below the transition temperature T 5 412 K.
