Fig. 2. Stokes shift relaxation function S(t) and time correlation functions C_g(t) and C_e(t) in ground and excited state in [Im₂₁][DCA] (top) and [Im₂₁][OTf] (bottom) for MQ (left) and C153 (right). The colored area corresponds to a 95% confidence interval. Experimental data (labeled EXP) are taken from ref. 69.
