The proton dynamics of solid 12-tungstophosphoric acid (TPA) is probed by solid-state 2H NMR in a temperature range from 293–503 K. Protons of TPA are shown to be involved in two types of molecular motion (see picture): the anisotropic local two-site flipping between the two possible orientations of the O[BOND]H bond at bridged oxygens of the Keggin anion, and the isotropic diffusion by hopping between neighboring surface oxygens of the anion.
