摘要：

Neutron diffraction with hydrogen/deuterium isotope substitution is used to investigate the water structure and the solute distribution in aqueous solutions of tetramethylammonium chloride ((CH3)4NCl) between 2.0 and 8.0 m concentrations at room temperature. The hydrogen-hydrogen (HH) pair correlation functions for the water indicate that the hydrogen-bonding geometry is not significantly changed over the concentration range compared to pure water, although the number of hydrogen bonds to nearest-neighbour water molecules decreases with increase in anion concentration. The results show no evidence of increased water structure compared to pure water in either the nearest-neighbour or the longer distance range.
