AbstractWe report full-dimensional state-to-state quantum mechanical (QM) and quasi-classical trajectory (QCT) calculations on the title reaction for the ground rovibrational initial state with total angular momentum fixed at zero on the accurate potential energy (PES) constructed recently by using permutation-invariant polynomial-neural network method (Li et al. in J Chem Phys 140:044327, 2014), to check the validity of the QCT method for the reaction. It is found that the QM state-to-state results strongly depend on the resonance structures in reaction, but the collision energy-averaged results show a smooth change with the increase of collision energy. Overall, the agreement between collision energy-averaged QM and QCT state-to-state results is satisfactory, in particular at high collision energy region, indicating that the QCT method is rather accurate on describing dynamics of the reaction on the PES. On the other hand, because earlier studies revealed the QCT results on the PES do not agree very well with the experimental measurements available, more theoretical and experimental studies should be carried out to achieve a full understanding on the dynamics of this benchmark complex-forming reaction.
