Abstract

Nuclear magnetic resonance studies revealed that the chemical shift of H2O in hydrated ionic liquids varied with their component ions. The variation reflected the formation of hydrogen bonding networks between ions and water molecules. The chemical shift relative to bulk water was used to quantitatively assess the kosmotropicity.
