DIFFRACTION AND X-RAY ABSORPTION STUDIES OF ELECTROLYTE-SOLUTIONS

Microscopic structures of electrolyte solutions over a wide range of concentration have been determined by three different techniques; X-ray diffraction, neutron diffraction combined with isotopic and isomorphic substitution, and X-ray absorption methods. Advantages and limitations in structural information obtained by the three methods are briefly described. The structures of some ionic solutions in room temperature liquid, undercooled, and glassy states have been revealed from comparative X-ray and neutron diffraction and X-ray absorption measurements. Physico-chemical data of the solutions are discussed from the microscopic structures of the solutions.
