Abstract
The four-photon polarization spectra of the Rayleigh wing of water and its isotopic molecules are recorded in the frequency range from 0 to 50 cm(-1). New resonances at +/-1.4 (in H2O) and +/-0.8 cm(-1) (in D2O) are found who se nature is not clear as yet. It is shown that the HDO molecule has no rot ational resonances in the 50% mixture of H2O and D2O, but H2O and D2O molec ules exhibit distinct rotational resonances, which correlates with the data on valence vibrations.
