Abstract
An analysis of the generalized frequency distribution of hydration wat er molecules in a 2M aqueous CsCl solution, extracted from results of an inelastic neutron scattering experiment, is presented. The signific ant area reduction of the low-frequency part and some shift of the lib ration mode to lower frequencies in comparison with pure water are fou nd, suggesting that Cs+ ion acts as a ''structure breaker'' disrupting the hydrogen bond network of water molecules comprising its hydration shell.
