Visualizing Chemical Dynamics in an Ionic Liquid Microdroplet using Ultrafast 2D IR Microscopy

The manuscript posted describes the first use of 2D IR microscopy to spatially resolve chemical dynamics in a complex chemical environment. Full details of the 2D IR microscopy experiments, sample preparation, data analysis, and modeling are provided. The results reveal how chemical dynamics evolve across a room temperature ionic liquid microdroplet. In addition, this work demonstrates the power of 2D IR microscopy to quantitative information hidden by other chemical imaging approaches.
