Af. Bunkin et al., ORIGIN OF LOW-FREQUENCY SPECTRUM STRUCTURE OF 4-PHOTON SCATTERING IN LIQUID WATER, Applied physics. B, Lasers and optics, 66(1), 1998, pp. 91-94
A multipeak structure of four-photon scattering spectrum in the range
from -2 to +2 cm(-1) has been found experimentally in liquid water. Th
e theoretical interpretation relates these spectral features to an int
erference of strictional and orientational contributions to the scatte
red signal.
