Abstract

It is shown that the difficulties in obtaining the correlation functions of rotational Ĝ2R(t) and vibrational Ĝv(t) relaxation associated with the construction of the profile of isotropic scattering from the observed profiles I *VV (ω) and I *VH (ω) with subsequent Fourier transformation of the constructed profile can be eliminated by a Fourier transformation of the profiles I *VV (ω) and I *VH (ω) directly with subsequent normalization of the obtained correlation functions G *VV (t) and G *VH (t) at the time t=0. The correlation functions Ĝ2R(t) and Ĝv(t) are obtained from the profiles of the Stokes and anti-Stokes Raman scattering lines. It is established that for lines with comparatively high polarization (p⊥ < 0.20) the correlation function Ĝ2R(t) and Ĝv(t) obtained by processing the observed profiles of the Stokes and anti-Stokes lines are almost identical.
