We finish the discussion of force fields developed for imidazolium-based systems by describing the work of Voth and co-workers who simulated [C2mim][N03] first with traditional fixed-charge models and then with a model that included electronic polarizability. For the fixed-charge system, Del Popolo and Voth used a force field having the AMBER function form, with parameters for the cation and anion taken from existing sources. They... [Pg.440]

Bhargava and Balasubramanian[142] carried out equilibrium MD simulations with a fixed charge model of 1,3-dimethylimidazolium chloride ([mmim][Cl]) at 425 K. Using a Green-Kubo expression (that is, the long-time integral of the stress-stress time correlation function) they obtained a viscosity for [mmim][Cl] that was about four times higher than the experimental value for [emim][Cl]. Apparently, there were no experimental data at this temperature for [mmim][Cl], but the authors assumed that the values would be similar to [emim][Cl]. [Pg.80]
