"Two dimensional ultrafast electronic spectroscopy of molecule and solid state systems"

ABSTRACT:

Two-dimensional electronic spectroscopy (2DES) monitors the flow of excitiation through a system energetically, spatially, and temporally. By generating correlation maps, this technique reveals the dynamics of electronic populations and coherence. In this talk, I will use 2DES to explore excitation dynamics in a synthetic analog of a molecular photosynthetic pigment in solution as well as presenting the first ultrafast electronic measurements of a solid state nitrogen vacancy diamond system. The observed anomalous response of the photosynthetic pigment system provides insight into the advantages of particular molecular architectures that are ubiquitous in nature. Experimental results on the solid state diamond system reveal relaxation dynamics and coupling between vibrational and electronic levels unveiling intriguing ultrafast dynamics.
