Abstract
We studied the diffusive motions of the protons in pure water and ZnCl2 aqueous solutions, using incoherent quasi-elastic neutron scattering. We showed that it is essential to take into account the rotational motion of the water molecules ; the associated characteristic relaxation time varies from 0.8 ps for H2O to 20 ps for the saturated solution which is interpreted in terms of hindered rotations for the concentrated solutions. The translational linewidth is conveniently fitted over the whole Q-range, using the Random Jump Diffusion model for which the jump length turns out to be roughly the same for pure H2O and the saturated solution, fairly close to the distance between protons in the water molecule.
