Solid state NMR spectra and quantum-chemical DFT calculations have shown the same local structure in crystalline and amorphous phases of poly(ethylene oxide)/LiCF3SO3 polymer electrolyte. For poly(2-ethyl-2-oxazoline)/AgCF3SO3 polymer electrolyte, 2/1 molar stoichiometry and a close contact between both components were found by NMR methods.

Spektra NMR pevné fáze a kvantově chemické DFT výpočty ukázaly tutéž lokální strukturu v krystalické a amorfní fázi polymerního elektrolytu polyethylenoxid/LiCF3SO3. Pro polymerní elektrolyt poly(2-ethyl-2-oxazoline)/AgCF3SO3 byla metodami NMR nalezena stechiometrie 2:1 a těsný kontakt obou složek.
