分子反应动态学是近二十年来化学动力学产生的一个分支学科,随着它的发展,物理化学、化学动力学教材的内容将面临着更新。本讲座拟较系统地介绍分子反应动态学的主要实验、理论方法、重要结果及应用前景。全讲座共设四讲:第一讲、化学动力学进入微观层次;第二讲、态-态反应的动态特征;第三讲、关于反应机理;第四讲、从微观到宏观。从本期起,将分三期连载(第三、四两讲合并在一期刊出)。 Molecular reaction kinetics is a branch discipline of chemical kinetics in recent twenty years. With its development, content of physical chemistry and chemical kinetics teaching materials will face an update. This lecture is intended to introduce systematically the main experiments, theoretical methods, important results and application prospects of molecular reaction kinetics. The lecture consists of four lectures: the first lecture, chemical kinetics into the micro-level; the second lecture, the dynamic characteristics of state-state reactions; third lecture on the reaction mechanism; the fourth lecture, from micro to macro. Starting from this issue, there will be a series of three installments (the third and the fourth two are combined and published in one issue).
