Abstract: Infrared investigations on H+ , Li+ , Cs+ and N(CH3) ionic forms of the perfluorosulphonate exchanger membrane, Nafion-117, in dry, H2O-wet and D2O-wet conditions have been carried out by transmission and ATR techniques. Correct interpretation of splitting of the 980 cm-1 band and the shift, of the 1056 cm-1 band on drying have been given in terms of relative hydration and the electron withdrawal (from –SO) by bare cations, respectively. Spectra in the OH and OD stretching regions have been interpreted taking into account the interaction between fluorocarbon network, hydrophobic interaction for N(CH3)] and sulphonate group hydration.
