A numerical analytical investigation of the shock forced oscillator (SFO) model as applied to the "diatomic molecule AB-structureless particle M" system is continued. The SFO model is based on the quan tum theory of strong perturbations and allows one to estimate probabilities for the transitions from level i to level f of diatomic molecule AB. The numerical analysis was carried out by the example of the nitrogen molecule N 2 , with anharmonic description of the internuclear interaction potential. The intermolecular interaction potentials in the N 2 -N 2 system are numerically analyzed using the Morse potential, the classical Lennard Jones potential, and the "improved" Lennard Jones potential.
