  • Raman Resonance Effect in liquid water.
    The journal of physical chemistry. A, 2008
    Co-Authors: Marcin Pastorczak, Marcin Kozanecki, Jacek Ulanski
    Abstract:

    Raman spectroscopy is a technique preferably used for studies of water structure because the proportions of intensities of main OH stretching modes are thought to reflect well a network of “intermonomer” hydrogen bonds as well as its disturbance by the presence of some solutes. The work presented herein demonstrates how the intensity ratio of two main components (around 3200 and 3400 cm−1) depends on the excitation wavelength in the visible range. Polarized Raman spectra indicate that the component at ca. 3200 cm−1 is in Resonance with light from the red range, which is in agreement with the presence of vibrational overtones in UV−vis absorption spectrum of water. These results are the first report on the occurrence of the Raman Resonance Effect in liquid water.
