Electromagnetic field effects on binary dimethylimidazolium-based ionic liquid/water solutions.
The non-thermal effects of electromagnetic fields in the microwave to far-infrared frequency on neat dimethylimidazolium chloride and triflate salts and their binary mixtures with water have been investigated by means of non-equilibrium molecular dynamics simulation. Significant alterations in dipole alignment and molecular mobility were found vis-à-vis zero-field conditions for mixtures of varying composition. Results indicate that the dimethylimidazolium and triflate ions respond most significantly to frequencies much lower than that of water in terms of dipole alignment and molecular mobility, and this was rationalized. in terms of dipole moment magnitudes, rotational inertia and translational field response.
