title: Hydration of ions in aqueous RbCl solutions.
abstract: Structural studies have been carried out on aqueous rubidium chloride solutions at three concentrations. Particle configurations consistent with neutron and x-ray diffraction data were obtained by reverse Monte Carlo modelling. By applying several coordination constraints, the generally accepted concept concerning the hydration of chloride ions could be tested in detail. The structural models generated may be made consistent with Cl(-) ions surrounded by six neighbouring water molecules, of which only three can connect to the ion via straight Cl...H-O (hydrogen bond) angles.
