• Applicant: Professor Dr. Ralf Giernoth

In continuation of our preceding research project within the SPP 1191 we are extending our work on the application of modern NMR spectroscopic techniques in ionic liquids to new methods. With these, we are going to study distances, interactions and dynamics of and in ionic liquids on a very fundamental level.Various NOE experiments will give insight into the interactions between ILs and solute molecules. These methods will—in combination with DFT calculations and MD simulations provided by cooperation partners within the SPP—also been used for the determination of molecular distances (or, more precisely, preferred probabilities of presence) in the liquid phase.The dynamics of ILs will be studied via diffusion NMR and compared with a variety of other spectroscopic and theoretical methods in cooperation with other groups within the SPP.
