局域模型中AB_2分子振动泛频能量弛豫的准经典轨线研究

Quasiclassical Trajectory Study of Vibrational Overtone Energy Decay in AB_2 Molecules in Local Mode Model

用准经典轨线法研究了局域模型中ＡＢ_２分子振动泛频能量的内部重新分配，用彭加勒截面考察了其相空间结构，讨论了局域模振动出现的可能性．

A derailed quasiclassiccd trajectory study is carried out for intramolecular vibrational energy redistribution of AB2 molecule in local mede model, and Poincare surface section is employed to analyze the phase space structure for the further understanding of energy decay. The Probability of the presence of local vibrational state is also discussed.
