NOE experiments for ionic liquids
Tools and strategies
The use of nuclear magnetic resonance (NMR)intermolecular nuclear Overhauser effect (NOE) representone of the most effective investigation tool for the assessmentof nanostructural organization in ionic liquids. Homo- andheteronuclear NOE provide, in principle, information on allthe possible interactions within the liquid: cation-cation,cation-anion, anion-anion and, in case, solute solventcontacts. Some paradigmatic cases taken from the recentliterature are exposed with the goal of outlining generalapproaches and strategies.
