Abstract

Vibrational coherence of the condensed-phase polyatomic molecules was studied by several types of femtosecond time-resolved spectroscopy. The Raman-active vibrational coherence in the ground-state was observed through optically-heterodyned impulsive stimulated Raman scattering (ISRS) spectroscopy. Transient ISRS experiment was also undertaken for the measurement of the low frequency vibrations of the excited state. In transient absorption spectroscopy carried out with a 40-fs time resolution, vibrational coherence was created by ultrashort pump pulses and the wavepacket motion in the excited state was observed for trans-stilbene and diphenylcyclopropenone.
