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.

在我们之前的SPP1191研究项目的继续下，我们正在将现代核磁共振波谱技术在离子液体中的应用扩展到新的方法。有了这些，我们将在非常基本的水平上研究离子液体和离子液体中的距离、相互作用和动力学。各种NOE实验将深入了解离子液体和溶质分子之间的相互作用。这些方法-结合SPP内合作伙伴提供的DFT计算和MD模拟-也将用于确定液体中的分子距离(或更准确地说，优先存在的概率)。ILS的动力学将通过扩散核磁共振进行研究，并与SPP内其他基团合作的各种其他光谱和理论方法进行比较。
