分子反应动力学如何走向21世纪

How Does Molecular Reaction Dynamics Go into the 21st Century

分子反应动力学领域正在发展之中，还远未进入成熟期。有些课题，如涉及对化学反应性基本理解方面的飞秒化学、立体化学动力学、务态化学、选模化学以及有关新反应类型方面的团簇化学动力学、自由基反应动力学、气－固表面反应动力学等皆处于它们发展的中间阶段。另外有些课题，如激光控制化学反应，则仅处于初创阶段。它们如何进入２１世纪呢？我们建议将来应该研究如下课题：（１）飞秒化学及立体态。态动力学；（２）激光控制化学反应；（３）团簇形成规律、结构及动力学；（４）分子高振动激发态光谱、自由基光谱及动力学；（５）理论研究。

The field of molecular reaction dynamics is growing,but it is far from reaching itsmaturity.Some of its subjects,such as femtosiecond chemistry,dynamical stcreo chemistty,state-to-state chemistry,mode selectivity chemistry which are concerned with the fundamental under-standing of the chemical reactivity,and cluster dynamics,free radical dynamics gas-surface dy-namics which relate to the new reaction types,are in the midst of their growing period。 Some sub-jects,for example,laser control chemistry,are only recently out of their infancy,How does it gointo the 21st century? We suggest that the topics we should study in the future are as follows:(1)femtosecond chemistry and dynamical stereo state-to-state chemistry;(2)laser control chemical reac-tions;(3)the formation rules, structures and dynamics of clusters;(4)structures,spectroscopiesand dynamics of high vibrational state of molecules and free radicals;(5)theoretical research.Thispaper gives a brief discussion about the topics mentioned above.
