Using 2D-Vibrational Electronic Spectroscopy to Probe Vibronic Coupling in Electron Transfer Processes

Literature seminar abstract

Investigating vibronic coupling is a crucial step towards a better understanding of certain electron transfer processes.  There is a growing consensus that ultrafast electron transfer does not conform to the Born-Oppenheimer approximation in non-equilibrium, condensed phase systems. 1 2D-Vibrational Electronic (2D-VE) Spectroscopy is used to probe vibronic coupling during electron transfer processes.2 2D-VE uses two IR pump pulses and a visible probe pulse to ascertain vibrational mode coupling to charge transfer. Analysis of 2D-VE spectra can give information about mode-specific vibronic coupling, vibrational coupling, vibrational relaxation, Franck Condon overlap, and electronic and vibrational frequency correlation overtime. In this talk, the application of 2D-VE to the model complex [(CN)5FeIICNRuIII(NH3)5]will be discussed.
