Polyatomic molecules have several electronic states that have similar energies. Consequently, their chemical dynamics often involve nonadiabatic transitions between multiple potential energy surfaces. Elucidating the complex reactions of polyatomic molecules is one of the most important tasks of theoretical and experimental studies of chemical dynamics. This paper describes our recent experimental studies of the multidimensional multisurface dynamics of polyatomic molecules based on two-dimensional ion/electron imaging. It also discusses ultrafast photoelectron spectroscopy of liquids for elucidating nonadiabatic electronic dynamics in aqueous solutions. (Communicated by Hiroo INOKUCHI, M.J.A.)
多原子分子具有多个能量相近的电子态。因此,它们的化学反应动力学通常涉及多个势能面之间的非绝热跃迁。阐明多原子分子的复杂反应是化学动力学理论和实验研究的最重要任务之一。本文描述了我们最近基于二维离子/电子成像的多原子分子多维多表面动力学的实验研究,还讨论了阐明水溶液中非绝热电子动力学的液体超快光电电子能谱。(由 INOKUCHI Hiroo 交流)
