TL;DR: In this article, room-temperature ionic liquids (RTILs) based on 1-butyl-3-methylimidazolium ([bmim]) with a variety of fluorinated anions were prepared, and the thermal behavior, density, viscosity, self-diffusion coefficients of the cations and anions, and ionic conductivity were measured over a wide temperature range.

TL;DR: The Lambda(imp)/Lambda(NMR) well illustrates the degree of cation-anion aggregation in the RTILs at equilibrium, which can be explained by the effects of anionic donor and cationic acceptor abilities for the RTils having different anionic andcationic backbone structures with fixed counterparts, and by the inductive and dispersive forces for the various alkyl chain lengths in the cations.

TL;DR: The dispersion interaction is found to be the major source of attraction in the benzene dimer and the orientation dependence of the dimer interaction is mainly controlled by long-range interactions.

TL;DR: In this paper, the performance of density functional theory using the Perdew and Wang's exchange and correlation functionals (PW91) functional for the prediction of intermolecular interactionenergies is evaluated based on calculations on the neon, argon, methane, ethylene, and benzene dimers, as well as on 12 hydrogen bonded complexes.

TL;DR: The oxidative stability of glyme molecules is enhanced by the complex formation with alkali metal cations, resulting in the highest occupied molecular orbital (HOMO) energy level lowering of a glyme molecule, which is confirmed by ab initio molecular orbital calculations.
