Conference paper


We have experimentally studied the molecular reorientational dynamics in a particular class of associated, hydrogen-bonded fluids [1]. Recently many different spectroscopic probes, such as EXAFS [2], inelastic and quasielastic neutron [3,4] and light [4,5] scattering, ultrasonic absorption [6], have demonstrated the existence of interesting structural effects taking place, at a local level, in aqueous solutions of 2–1 strong electrolytes of transition metals, like CuBr2, ZnCH2, NiCl2, CdCl2, Cu(NO3)2, at intermediate and high concentrations. This has been explained in terms of a progressive breaking of the local tetrahedral water H-bonded network, peculiar to very dilute solutions, and a contemporary appearence of a new short-range order, which reproduces the solute crystalline structure.
