## Abstract The IR and __Raman__ spectra and conformations of the ionic liquid 1‐ethyl‐3‐methyl‐1__H__‐imidazolium tetrafluoroborate, [EMIM] [BF~4~] (**6**), were analyzed within the framework of scaled quantum mechanics (SQM). It was shown that SQM successfully reproduced the spectra of the ionic

## Abstract Raman spectra of dilute solutions of acetonitrile in ionic liquids reveal the characteristic features of ionic liquids' polarity. This is accomplished by investigating the Raman bandshape of the ν (CN) band, corresponding to the CN stretching mode of CH~3~CN, which is a very sensitive p

## Abstract The ionic liquids 1‐ethyl‐3‐methylimidazolium tetrafluoroborate ([EMIM][BF4]) and 1‐methyl‐3‐propylimidazolium tetrafluoroborate ([PMIM][BF4]) were studied by H,H‐NOESY NMR using a cross‐relaxation matrix analysis. Cross‐peak intensities are seen to increase with increasing mixing time.
