Ultrafast vibrational spectroscopy of photochemistry and anharmonic coupling

Monday, April 13, 2009 (All day)
Dr. David McCamant

Research in the McCamant lab focuses on ultrafast nuclear dynamics in photochemistry and photobiology, with the hope that we can illuminate how excited-state structure and vibrational energy flow are related to photochemical function. Our work is conducted talong two integrated themes: (1) ultrafast electronic and vibrational studies of photochemical reaction dynamics of DNA and (2) development of new spectroscopic techniques to study vibrational coupling. This talk will focus on a new femtosecond two-dimensional spectroscopy that we have developed to probe vibrational coupling over a large spectral window. Experimental results and a theoretical basis founded upon anharmonically coupled harmonic oscillators will be presented.
