Structural study of low concentration LiCl aqueous solutions in the liquid, supercooled, and hyperquenched glassy states

""Neutron diffraction experiments on a solution of LiCl in water (R = 40) at ambient conditions and in. the supercooled and hyperquenched states are reported and analyzed within the empirical potential. structure refinement framework. Evidence for the modifications of the microscopic structure of the. solvent in the presence of such a small amount of salt is found at all investigated thermodynamic. states. On the other hand, it is evident that the structure of the hyperquenched salty sample is similar. to that of pure low density amorphous water, although all the peaks of the radial distribution functions. are broader in the present case. Changes upon supercooling or hyperquenching of the ion’s hydration. shells and contacts are of limited size and evidence for segregation phenomena at these states does. not clearly show up, although the presence of water separated contacts between ion of the same sign. is intriguing.""
