Abstract

Mixtures of the ionic liquid (IL) [C(6)mim](+)[Tf2N](-) and acetonitrile have been investigated by a combination of dielectric relaxation spectroscopy (DRS) and ultrafast transient absorption techniques using the molecular probe 12'-apo-beta-carotenoic-12'-acid (12'CA). Steady-state absorption spectra of the 12'CA molecule have also been recorded. The position of the probe's S-0 -> S-2 absorption ...
