Abstract
Infrared and NMR measurements on solutions of lithium and cesium dinonylnaphtalene sulfonates (DNNS-salts) in heptane show that the state of water in these systems is in several respects similar to its state in solid ion exchange resins and in some respects also similar to that in ordinary water. The two cations differ in their interaction with the sulfonic acid group at low water contents, the interaction being stronger for Li+. Spin-lattice relaxation measurements on LiDNNS show that the state of lithium both in DNNS and in solid resins is quite different from that of lithium salts in aqueous solutions of the corresponding concentration.
