摘要
采用准经典轨迹法,考察了H2O及H2S分子简正模激发态下分子内各态能量随时间变化的分布关系,讨论了激发能在各态间的转移规律.研究表明:简正模激发态能量转移倾向于频率彼此相近或对称性相同的态间.
Qausiclassical trajectories QCT have been used to investigate energy transfer of various excited H X(X=O,S) stretching and H X H bending normal modes in H 2O and H 2S, respectively. Average energy in each normal mode as a function of time is obtained. The results demonstrate that only those modes with frequencies close to or with the same vibrational symmetry as that of the excited mode participate in the energy transfer.
