Collective translational motions and cage relaxations in molecular ionic liquids

摘要: In this computational study, the collective translational motions of 1-ethyl-3-methylimidazolium triflate, characterized by its current correlation function and dipolar displacement, are interpreted in terms an ion cage around a central ion. Thereby, coincidence relevant time constants is observed. Furthermore, long living composition rather heterogeneous. Besides high numbers counter ions, several ions like charge populate first shell contrast to strong influence local environment on motion, rotations strictly collective. other words, picture falls short describing overall antiparallel alignment ionic dipoles. A further issue work interpretation initial region displacement. It can be related all processes showing up dielectric spectrum. particular, slow which invisible detected. The inclusion these allow for excellent reconstruction experimental spectrum generalized constant.
