Resolved Structure within the Broad-Band Vibrational Raman Line of LiquidH2O from Polarization Coherent Anti-Stokes Raman Spectroscopy

Abstract
We have resolved individual components of the broad vibrational band of liquid water by using polarization coherent anti-Stokes (active) Raman spectroscopy. None of the existing models of liquid water based on the unresolved spontaneous Raman spectrum describe in full the observed spectra.
