We report tests of some new symplectic integration routines of sixth and eighth order applied to the integration of classical trajectories for a triatomic model molecule. This system has mixed regular and chaotic phase space. Especially for long-lived trajectories, which are trapped in the stochasti

In this article we observe that generally symplectic integrators conserve angular momentum exactly, whereas nonsymplectic integrators do not. We show that this observation extends to multiple timesteps and to constrained dynamics. Both of these devices are important for efficient molecular dynamics
