Abstract

A new experimental method for ultrafast time-resolved pump-probe Raman spectroscopy by use of temporally incoherent light is proposed. It is predicted that the temporal resolution of this pump-probe Raman experiment is not determined by the duration of pump and probe pulses but by the cross-correlation time between pump and probe lights. This idea is experimentally examined for Raman scattering from electronically excited trans-stilbene in n-hexane solution. In accordance with the prediction, the picosecond decay of the Raman band at 1560 cm-1 arising from the stilbene molecules in the S1 state is observed by use of nanosecond pump and probe pulses, while no decay is observed for the Raman bands of the solvent.
