Determination of inter‐ionic and intra‐ionic interactions in a monofluorinated imidazolium ionic liquid by a combination of X‐ray crystallography and NOE NMR spectroscopy

Abstract

We report the very first application of a Transient 1D ¹ H{¹⁹ F} NOE NMR experiment in neat ionic liquids. In comparison with classical 2D HOESY NMR spectroscopy, a substantial reduction in measurement time is gained with comparable quality and information content of the spectra. In combination with classical X-ray crystallography, we have applied this technique for the determination of inter-ionic distances (i.e. probabilities of presence) utilizing an ionic liquid containing a monofluorinated imidazolium cation.
