In sum, several tests showed that PES-2023 presents great versatility and capacity to describe the dynamics behaviour of this ten-body polyatomic system. In addition, it should be noted that PES-2023 can also be used in kinetics studies, which will be addressed in the near future. the CN + CH4 reaction using PES-2017 (dashed line), taking as reference the respective equilibrium geometry, 180º. Note that the remaining parameters at the respective saddle points were kept at the reference system.
