摘　　要：The dynamics of tripartite entanglement and intramolecular energy for one harmonic- and two anharmonic-vibrational modes in a symmetric trimer molecule is studied for various initial states, where the entanglement is quantified in terms of concurrence and the interacting energy among three modes is calculated to establish a link between entanglement and energy. It is shown that the concurrence and the interacting energy behave dominantly positive correlation for the localized state in the anharmonic-vibrational mode, while they are domi- nantly anti-correlated for the localized state in the harmonic-vibrational mode. The relation between bipartite entunglement and the energy in a subsystem is diseussed as well. Those are useful for quantum computing and quantum information in high dimensional states prepared in polyatomic molecules.
