Due to their structure, ionic liquids exhibit additional levels of ordering beyond those found in common molecular liquids. Polarized 2D IR and pump-probe experiments have been conducted on a molecular anion probe in a series of room-temperature ionic liquids with various cation alkyl chain-lengths. The analysis of these ultrafast experiments characterizes the effects of the growing viscosity and polar-apolar ordering on ion solvation and ionic liquid structure and dynamics
