Resolution of dynamic processes in proton-conducting 12-tungstophosphoric acid 14-hydrate by a combination of quasielastic neutron-scattering and n.m.r. techniques

Abstract

Combination of variable temperature incoherent quasielastic neutron-scattering (q.e.n.s.) and 1H n.m.r. relaxation time measurements allows the characterisation of dynamic processes associated with proton transport in 12-tungstophosphoric acid 14-hydrate; q.e.n.s. identifies 180°-flips of H2O and enables n.m.r. data to be interpreted in terms of this reorientation and H+ self-diffusion [Dt(295 K)∼ 10–7 cm2 s–1].
