N2 - Femtosecond Kerr-gated emission spectroscopy and picosecond time-correlated single photon counting are used to measured the full solvation response of 4-dimethylamino-4′-cyanostilbene in three imidazolium ionic liquids. The liquids studied are comprised of the 3-butyl-1-methylimidazolium cation '(Im41+)' and the anions hexafluorophosphate, bis(trifluoromethylsulfonyl)imide ('Tf2N-'), and tris(trifluoromethylsulfonyl)methide ('Tf3C-'). In all three liquids the solvation response is widely distributed in time with important contributions extending from 100 fs to 10 ns. The amplitude of the fastest (<1 ps) portion of the dynamics is correlated to the relative size and/or mass of the anion and it increases in the order Tf3C-
