Low frequency dynamics in water and ZnCl 2 solutions by quasi-elastic and inelastic neutron scattering

In this paper we report the results of a study of the low frequency dynamics in H 2O and aqueous solutions of ZnCl 2 as a function of temperature; the results were obtained by quasi-elastic and inelastic neutron scattering using the IN6 time-of-flight spectometer at I.L.L., Grenoble. The temperature...

Summary:In this paper we report the results of a study of the low frequency dynamics in H 2O and aqueous solutions of ZnCl 2 as a function of temperature; the results were obtained by quasi-elastic and inelastic neutron scattering using the IN6 time-of-flight spectometer at I.L.L., Grenoble. The temperature dependence of the frequency distribution functions for pure H 2O and the saturated ZnCl 2 solution is shown. A discussion about the influence of the choice of the value of the rotational diffusion coefficient D r on the results from the fit of the quasi-elastic part of the spectrum of the ZnCl 2 solution is presented. In particular, we stress the necessity of collateral experimental evidence, such as we obtained by depolarized Rayleigh wing scattering.
