Infrared spectra in the "CN-stretch" region of the SCN- anion, for NaSCN and LiSCN, dissolved in polyethylene oxide dimethylether (PEO-400) of average molar mass 400, show dramatic differences from the infrared spectra of the same electrolytes dissolved in polyethylene oxide glycol (PEG-400) of average molar mass 400. The differences are attributed to anion solvation by the -OH end of the PEG polymers. Similar comparison of the molar refraction R of the two electrolytes dissolved in the two solvents, also shows dramatic differences in the values and concentration dependence of the R(NaSCN) and of R(LiSCN) between the two polymer solutions. These differences are also attributed to anion H-bonding solvation by PEG-400. The different molecular status of the above electrolytes in the two solvents, should be considered, when planning their use as ion transport media in polymer-electrolyte batteries.
