Abstract

The low-frequency motions in ionic liquids can be studied by transmission and attenuated total reflection spectroscopy in the THz region (see spectrum for 1). These motions involve flexing of individual ions and intermolecular interactions by hydrogen bonding. Combined measurements show that the degree of hydrogen bonding is crucial for the solid structures of this material.
