NMR studies of the cubic hydrogen bronze Hx WO3 have confirmed the hydrogen location proposed by Dickens et al. The diffusion of protons is limited by the availability of a framework of suitable oxygen sites and was found to contain elements of reduced dimensionality. The activation energy is of the order of magnitude of 40–50 kJ/mol, and the preexponential factor amounts to about 10‐13 s as usual. A “prefactor anomaly” observed in several other studies may arise if the dimensionality of the motion is not considered. Comparison with hydrogen bronzes HxMoO3 is discussed.
