Abstract: Classical trajectories of diatomic system N2 are calculated by means of both Symplectic and R-K algorithms.It is shown that Symplectic algorithm keeps Symplectic structure of the system and its intrinsic qualities unchanged and consistent with the theory and experiment. R-K approach is not the case.

Key words: Diatomic system, Classical trajectory approach, Symplectic algorithm
