H chemical shift spectroscopy has been used to determine the diffusing species in layered and defect pyrochlore structures of HNbWO,.xH,O (x= 1.5, 1). A narrow signal at S= 1 I .3 ppm in the former indicates the presence and diffusion of H,O+ ions, while for the latter compound 6= 7.7 ppm, implying

In the present 'H-n.m.r.-studies, we investigated the dynamics of the spins associated with the narrow component of the absorption lineshape of solid cyclohexaamylose (alpha cyclodextrin) .6 H,O. The presence of dipolar interactions in both the narrow and the broad components of the lineshape is dem
