After reviewing the properties and structure of ionic liquids, leading specialists explore the role of these materials in optical, electrochemical, and biochemical sensor technology. The book then examines ionic liquids in gas, liquid, and countercurrent chromatography, along with their use as electrolyte additives in capillary electrophoresis. It also discusses gas solubilities and measurement techniques, liquid-liquid extraction, and the separation of metal ions. The final chapters cover molecular, Raman, nuclear magnetic resonance, and mass spectroscopies.

A number of nuclear magnetic resonance (NMR) textbooks and review articles that focus on the dynamics in supercooled liquids comprised of organic molecules [2,11,12,15], on polymer specific dynamics [71-75], and on ionic or inorganic glasses [76-79] exist. In these contributions, the theoretical background of NMR techniques and models of molecular motion have been comprehensively discussed. Therefore, we curtail the theoretical part and concentrate on selected NMR techniques applied most frequently to the investigation of molecular glass formers. 

The immobilization of ionic liquids (ILs) is intimately connected with spectroscopy, with the goal to characterize the support, the IL film, or the catalyst. Besides the characterization by BET surface methods and catalytic activity, the most powerful tools are nuclear magnetic resonance (NMR) spectroscopy and infrared (IR) spectroscopy, which are discussed separately in the following. NMR spectroscopy is mostly performed in the solid state, where either the support itself or the IL film with the dissolved catalyst therein is characterized. For the latter case, some liquid-state NMR experiments are also applicable. Besides the characterization of the SILP system itself, solubility effects of the reactants using liquid-state NMR are well established to understand the kinetics. Those examinations are beyond the theme of this chapter and are therefore not discussed here.

This review presents recent developments in the application of nuclear magnetic resonance (NMR) spectroscopy to study ionic liquids. In addition to routine structural characterization of synthesized ionic liquids, availability of multitude of advanced NMR techniques enables researchers to probe the structure and dynamics of these materials. Also most of the ionic liquids contain a host of NMR-active nuclei that are perfectly suitable for multinuclear NMR experiments. This review focuses on the application of NMR techniques, such as pulsed field gradient, relaxometry, nuclear Overhauser effect, electrophoretic NMR, and other novel experiments designed to investigate pure ionic liquids and the interaction of ionic liquids with various salts and solutes.
