“…This work considers ionic liquids based on the 1-ethyl-3-methylimidazolium cation, [C 2 C 1 im] + , and a sequence of cyanate-anions of increasing symmetry: thiocyanate, [ 4 ] − . The [SCN] − anion has been already the subject of several Raman band shape studies of alkali cation salts in aqueous solution and high temperature molten state [15][16][17][18][19]. The CN band shape in [C 2 C 1 im][SCN] is expected to differ from molten alkali thiocyanates because of differences in cation size and temperature, so that the analysis allows for interesting comparisons between the ionic liquid and high temperature molten salts.…”
