Coriolis and anharmonicity couplings in the intramolecular vibrational energy flow: H+3potential

摘要

A classical study was conducted on the effects of Coriolis coupling on the internal energy flow between the two degenerate normal mode oscillations of H+3. Strong correlations between the energy flow and the types of trajectories with the direction of the molecular rotation are revealed. The angle at which a trajectory, near its onset, approaches the isoenergetic contour on the potential surface is shown to determine the type of the trajectory and general characteristics of the system.
