Picosecond resonance Raman spectra of the S 1 states of trans-stilbene and its torsionally hindered analog 2-phenylindene in solution show that the vibrational cooling times in these two systems are similar. Anti-Stokes scattering from high frequency modes is observed for the first time and provides
We report the observation of quantum interference effects in the energy-resolved fluorescence decays of the second excited singlet state ofjet-cooled azulene. The results are analyzed and discussed in terms of a real-time view of intramolecular vibrational relaxation.
