“分子反应动力学”是国家自然科学基金“七五”重大项目,开展了八个课题的研究,并取得一些新的进展。本文主要介绍:分子束反应动力学,激光光谱和分子间碰撞传能,自由基和激发态分子的产生及反应,以及激光诱导的表面反应动力学等方面研究进展。 “Molecular Reaction Kinetics” is a major project of the National Natural Science Foundation of China during the “Seventh Five-Year Plan” period. Eight research projects were carried out and some new progresses were made. This paper mainly introduces the research progress of molecular beam reaction kinetics, laser spectroscopy and collision energy transfer between molecules, the generation and reaction of free radical and excited state molecules, laser induced surface reaction kinetics and so on.
