Bending and stretching : The nature of intermolecular interactions in imidazolium‐based ionic liquids has been studied by far‐infrared spectroscopy. The lowest frequencies can be assigned to the bending and stretching vibrational modes of the cation–anion interaction, which describes the cohesion energy.
