Oral: New Multispectral Multidimensional Coherent Spectroscopies for Studying Ultrafast Photochemical Dynamics in Condensed Phases

Understanding the evolution of ultrafast photochemical and photophysical dynamics is a most fundamental challenge in chemistry and physics. Obtaining a complete and global picture of a nonequilibrium, excited state process is particularly difficult to achieve when the process of interest involves multiple degrees of freedom of very different types, which also may occur on quite different timescales. Coherent multidimensional spectroscopy offers a direct route to correlating excited motions with multiple degrees of freedom throughout a photochemical process. This talk will include progress in developing new coherent multidimensional spectroscopies that are geared towards measuring photochemical processes in the condensed phase, such as nonadiabatic dynamics in the vicinity of conical intersections, core-valence electronic correlations, and coherent charge migration.
