Ionic liquids from the bottom up: local assembly motifs in [EMIM][BF4] through cryogenic ion spectroscopy.


To clarify the intramolecular distortions exhibited by the complementary ions in the archetypal ionic liquid 1-ethyl-3-methylimidazolium tetrafluoroborate [EMIM][BF4], we report the vibrational spectra of the isolated ionic constituents and small aggregates cooled to about 10 K. Deuteration of bare EMIM(+) at the C(2) position, the putative hydrogen bond… (More)
