1. Multicolor IR spectroscopy of pure liquid water

Author

Abstract

Multicolor infrared ultrafast spectroscopy is applied to investigate the vibrational relaxation dynamics in liquid water at room temperature with both the stretching and the bending mode being photoexcited and probed. A unified model, capable of the reproduction of as much as 150 transients, yielded cross-sections and relaxation times for the stretching and bending modes. It is demonstrated, that the energy from the initially excited stretching vibration is partitioned to the bending modes of approximately two water molecules.

Abstract

The ultrafast dynamics of water nano-droplets (1-10 nm size) of the L-2-phase of the ternary mixture H2O-AOT-CCI4 have been studied using frequency-resolved mid-infrared pump-probe spectroscopy in the spectral region of the OH-stretching vibration.
