Hi Francesco,
This seems to be a spin-crossing/spin-forbidden reaction.
With conventional pure QM treatment, we need to calculate two PES of
different spins along the reaction path and to see where two spin states
cross.
Please refer to Professor Truhlar's recent work "Phys. Chem. Chem. Phys.,
2018,20, 4129-4136" and its references.
Hope it helps.
Best,
William
