Abstract
The frequency-angular spectrum of nonlinear light scattering in water in the region of the second optical harmonic of picosecond Nd3+YAG laser radiation is studied. It is shown that this scattering occurs by the four-photon interaction mechanism. Statistical treatment of the spectra of four-photon scattering in the collinear interaction mode revealed a structure related to the frequency of infrared radiation caused by vibrations of cluster complexes of water molecules.
