摘要：

Raman spectra of poly(ethylene oxide) oligomers complexed with alkali metal triflate salts have been measured as a function of chain length, salt concentration and temperature. Spectral changes in the oligomer bands accompanying complexation are attributed to a conformational arrangement of the polyether backbone not observed in the pure liquid. An anomalous chain length dependence is discussed in terms of cation coordination with the polyether oxygen atoms.
