Abstract

Starting from the infinite-order sudden approximation, the tetradic collisional relaxation cross- sections may be expressed in terms of dyadic cross-sections. It is shown that the energy corrected sudden approach leads to a correct prediction of the spectral profile unless the characteristic macroscopic relaxation times are introduced in the model. Consequently, a few number of fitting parameters allows us to predict infrared, stimulated Raman or Coherent Antistokes Raman profiles within the experimental accuracy. The generalization to any excited vibrational mode is straightforward.
