Spectrum chemical hfip
WebThe shift in the –OH stretching vibration indicated the existence of hydrogen bonding between ChCl and HFIP. In addition, compared with the spectra of ChCl and HFIP, both characteristic peaks were distinguishable in the ChCl/HFIP spectra. Furthermore, no new peaks were detected, indicating that there was no chemical reaction during DES synthesis.
