Transient Vibrational Spectroscopy

Femtosecond stimulated Raman spectroscopy (FSRS) is a powerful technique for observing the excited-state structural evolution of a system. First, a photochemical process is initiated by pumping the system with a femtosecond actinic pulse. Then, stimulated Raman scattering (SRS) is used to probe the vibrational spectrum of the excited-state surface. The SRS probe uses a picosecond Raman pump and broadband femtosecond Raman probe pulse.  Changing the time delay between the actinic pump and the SRS probe allows one to probe the evolution of the vibrational spectrum on the excited-state surface.

 

These experiments are being done in collaboration with Tullio Scopigno and the Femtoscopy Lab at the University of Rome-La Sapienza.
