Abstract
For pt.I see ibid., vol.20, p.1573 (1987). The technique of high-resolution incoherent quasielastic neutron scattering (QENS) is used to measure the translational diffusive motion of water protons in concentrated NiX2, CuX2 and NdX3 aqueous solutions in which X=Cl−, ClO4−and/or NO3−. The technique of tracer diffusion is also used in order to measure the cation selfdiffusion coefficient in concentrated NiX2 and CuX2 aqueous solutions in which X=Cl−and ClO4−. It is shown that at room temperature (approximately=25 degrees C) the cation-water proton binding times are described by the limits tau 1(Ni2+)>or approximately=5*10-9s, tau 1(Cu2+)<or approximately=10-10s and tau 1(Nd3+)>10-10s and that for the Ni2+solutions, which are in slow exchange, the diffusion coefficient of protons bound to the cation is measurable using the QENS method.
