(top) Optimum interaction energies, as a function of the dielectric constant, for the hydrogen-bonded (C2–H(D)) and “stacked” [EMIM]–acetone and [EMIM]–DMSO structures. (bottom) Two configurations of the C2–H(D) hydrogen-bonding structure of [EMIM]–DMSO (ε = 12.5). (1) Optimal interaction energy structure (green carbons). (2) Structure corresponding to the maximum infrared red-shift (blue carbons). Distances are in Angstroms, and angles are in degrees.
