Quasielastic Neutron Scattering

The dynamics of H2O molecules and NH4+ ions in a new type of crystalline proton conductor (NH4)2(adp)[Zn2(ox)3]·3H2O has been investigated by quasielastic neutron scattering techniques to elucidate the proton conduction mechanism.

Abstract The following paper comprises a survey of the role neutron scattering methods have played to help understand the origins of the diverse properties of electrolyte solutions which contain transition metal cations. It is seen how neutron diffraction and isotopic substitution is able to resolve the local structure around contrasting ions, such as Cr3+ , Ni2+, Fe3+ , Fe2+, Cu2+, without recourse to sophisticated modelling procedures. Quasielastic neutron scattering (QNS) provides insight into the dynamics of the protons in solution. The results enable one to distinguish between cations whose water molecules are coordinated on time scales larger than 5 x 10-9 s, shorter than 10-10s, or intermediate between those two limits. QNS also provides information on the existence of a second relatively short-lived hydration shell distinct from the bulk water.
