ABSTRACTA comparative infrared spectroscopic study of the local vibrational potential energy environment of the CF3SO3 (triflate) anion in the poly(ethylene oxide)-lithium triflate and poly(ethylene oxide)-sodium triflate systems is presented. Analysis of the crystalline stoichiometric compounds in the two systems identifies significant differences in the ionic association. Comparison of the relative percentages of the anionic species in the PEO-NaTf system at various concentrations suggests that crystalline compound formation may proceed through intermediate structures. A symmetry-based vibrational analysis is applied to the crystalline compounds.
