Abstract
H-1 Magic Angle Spinning (MAS) NMR of layered HNbWO6 . xH(2)O (x = 1.5 , 0.5) is carried out at room temperature and at various spinning spee ds (1-12 kHz). Results on the fully hydrated sample (x = 1.5) are cons istent with the model of diffusion of H3O+ ions within the layers. In the partially dehydrated sample (x = 0.5) an exchange between the dist inctly present cage protons and H3O+ protons leads to protonic conduct ion.
