The paper provides experimental and theoretical results of stimulated Raman
 scattering Stokes component indicatrix asymmetry study. Theoretical results demonstrate
 that asymmetry is caused by influence of Stokes/anti-Stokes parametric processes.
 Stokes/anti-Stokes parametric process provides additional photons to the forward Stokes
 component. This excess of photons compared to a backward Stokes component increases
 due to combinational mechanism of stimulated scattering during further propagation of
 waves along the medium. Thus, under competition of forward and backward Stokes
 components generation, the process of forward stimulated Raman scattering takes
 significant advantage. Obtained in this paper is satisfactory matching between theoretical
 calculations and experimental results for benzene under excitation by laser pulses with
 the duration 25 ns and wavelength 694.3 nm.
