摘要: 通过研究HOC1分子高激发振动态的动力学势,明确了该体系的动力学特点.研究表明,在O-C1伸缩模式和H-O-C1弯曲模式间存在2:1 Fermi共振的动力学模型下,H-O伸缩振动模式对于上述两种振动模式的动力学势有显著影响,且这种影响随Polyad数呈现有规律的变化.作为定量研究,还研究了Polyad数为24时该分子体系的动力学势与各能级的相空间轨迹.分析表明,相空间轨迹与动力学势中的动力学不动点有很好的对应关系.此外,将该Polyad数下的动力学势中的能级按照相空间轨迹的作用量积分进行分类,明确了这些能级所处的量子环境.Abstract: The dynamical potentials of highly excited vibrational states of HOC1 in the bending and O--C1 stretching coordinates with anharmonicity and Fermi coupling are studied. The result shows that H----O stretching vibration mode has significantly different effects on O----C1 stretching mode and H---O---C1 bending mode under different polyad numbers. The dynamical potentials and the corresponding phase space trajectories are studied in the case that the polyad number is 24 and it is found that the quantal vibrational energy levels could be classified by the fixed points of dynamical potentials and the quantum environments could be identified by the numerical values of action integrals.
