摘要：
The strength of the interaction between anions and cations in protic ionic liquids (PILs) can be extracted from far-IR spectra. A suitable set of specially synthesized PILs was used to correct the frequency shifts of these low vibrational modes for contributions resulting from changing reduced masses only. The experimental results were confirmed by DFT calculations. Copyright © 2013 WILEY-VCH Verlag GmbH & Co. KGaA, Weinheim.
