Ultrafast vibrational spectroscopy of photochemistry and anharmonic coupling

Monday, April 13, 2009 (All day)
Speaker: 
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.
