Stimulated Mandelshtam-Brillouin light scattering and nonlinear absorption in an aqueous solution of nonelectrolyte

The influence of two-photon absorption on the stimulated Mandelshtam-Brillouin scattering of light in (beta) -picolin- water solution with a singular point has been studied. Values of two-photon absorption coefficient and the imaginary part of a susceptibility of the solution have been calculated. Temperature dependence of the imaginary part of the susceptibility for analyzed solution has been determined.
