In this project in the Physical Chemistry program of the Chemistry Division, Professor Ahmed H. Zewail of the California Institute of Technology will continue a series of investigations in his research program on the dynamics of molecular energy redistribution and reactions. Four specific areas are planned for investigation: 1) Study of the intramolecular vibrational energy redistribution (IVR) in reactive and non-reactive systems with particular attention given to mode specificity, its nature and time scale, the roles played by rotations and collisions, and the influence of symmetry; 2) study of the reaction rates and intermediates of elementary systems, emphasizing the effects of total energy, mode specificity, and the role of angular momentum; 3) study of the elementary dynamics in complex systems, with applications to organic and organometallic systems; and 4) theoretical investigations of IVR, reaction rates and molecular dynamics. These investigations are at the forefront of contemporary physical chemistry, dealing with fundamental aspects of chemical reactions and dynamics on a molecular scale.

在化学系物理化学计划的这个项目中，加州理工学院的Ahmed H.Zewail教授将在他的研究计划中继续进行一系列关于分子能量重新分配和反应动力学的研究。计划研究四个具体领域：1)研究反应性和非反应性体系中的分子内振动能量再分配(IVR)，特别注意模式特异性、其性质和时间尺度、旋转和碰撞所起的作用以及对称性的影响；2)研究基本体系的反应率和中间体，强调总能量、模式特异性和角动量的作用；3)研究复杂体系中的基本动力学，并将其应用于有机和有机金属体系；以及4)IVR、反应率和分子动力学的理论研究。这些研究处于当代物理化学的前沿，涉及分子尺度上的化学反应和动力学的基本方面。
