In a project led by Huix-Rotllant, my colleague at the theoretical chemistry team in Marseille, Falahati and co-auhtors employed quantum wavepacket dynamics using the Multi-Layer MCTDH method with a high-dimensional vibronic Hamiltonian fitted to CASPT2 data to elucidate this process. Their model incorporated 179 electronic states spanning singlet, triplet, and quintet manifolds, coupled to 15 vibrational modes, enabling the accurate description of nonadiabatic dynamics.
