Intramolecular Vibrational Energy Redistribution Measured by Femtosecond Pump-Probe Experiments in a Hollow Waveguide

We report femtosecond pump-probe experiments to investigate the intramolecular vibrational energy redistribution in the gas phase for CF3CHFI, CHBrFI, CHBrClF and benzene (C6H6). To increase the measured probe signal the experiments have been performed in a hollow waveguide.
