Freezing the Motion in Hydroxy-Functionalized Ionic Liquids – Temperature Dependent NMR Deuteron Quadrupole Coupling Constants for two Types of Hydrogen Bonds far Below the Glass Transition

We measured the deuteron quadrupole coupling constants (DQCCs) for hydroxy-functionalized ionic liquids (ILs) with varying alkyl chain length over the temperature range between 60 and 200 K by mean...
