It’s theoretically proved that in self-focusing mode of exciting radiation, selfphase
 modulation, and the relaxation oscillations of the nonlinear polarization amplitude,
 the frequency-angular structure of the parametric components of the stimulated Raman
 scattering has special features. Maximum of radiation energy shifts relative to Raman
 frequencies, and this shift depends on the scattering angle. The largest Stokes shift (about
 -10 cm⁻¹
 ) of the maximum energy in the spectrum of parametric components
 corresponds to axial radiation and is determined by the size of the focal area, time of
 polarization existence as well as mismatch of the polarization wave vectors and
 parametric component. The obtained estimations of the self-phase modulation influence
 on radiation in the case of relaxation oscillations show that this influence is insignificant.
 The effect has been interpreted in terms of short-term phase matching.
