Hydration and Intermolecular Interaction: Infrared Investigations with Polyelectrolyte Membranes focuses on the intriguing possibilities of ion-exchange resins.This book explains that water-containing ionized resins are unique models of electrolyte solutions that enable the study of water behavior in the solvation sphere without interference from the bulk of solvent. The topics discussed include assignment of the IR bands, free water molecule, electron structure of the anions in the salts, and removal of antisymmetric stretching vibration. The measurements on polystyrenesulfonic acid as a function of degree of hydration, preparation of membranes for IR spectroscopy, and IR investigations at low temperatures are also deliberated.This publication is beneficial to chemists, electrochemists, and spectroscopists.
