The quantification of solvent effects is an important tool to understand physicochemical phenomena in solution. According to Gutmanns' “donor–acceptor concept”, the donor number is a measure for the tendency to donate electron pairs to acceptors, and the acceptor number a measure for the electrophilic properties of a solvent. To achieve a better understanding of the complex solvent–solute relationship in ionic liquids, donor and acceptor numbers for a series of 36 imidazolium‐based ionic liquids have been determined by using 23 Na and 31 P NMR spectroscopy.
