The polar domains within model ionic liquids are assessed by intermolecular NOE interaction studies. The cation–cation distances in pure ionic liquids 1‐butyl‐3‐methylimidazolium (see picture) and 1‐butyl‐2,3‐dimethylimidazolium tetrafluoroborate are obtained and used to provide models of the local structure of the liquids.
