An Infrared Spectroscopy Study of the Conformational Evolution of the Bis(trifluoromethanesulfonyl)imide Ion in the Liquid and in the Glass State

Figure 5

Temperature dependence of the ratio of the intensity of the vibration lines due to the transoid and cisoid conformers and best fit lines. In the inset two examples of the quality of the fit for the low frequency and high frequency lines are reported.
