性质:又称微观化学动力学,分子动态学,化学基元反应动态学。是化学动力学中涉及微观化学反应的一个新兴学科分支。它借助于分子束、激光等新兴技术,对化学反应进行微观的、分子水平的和量子状态的研究。它可研究个别分子间的单次碰撞及反应行为,获知具有特定能态及方位的反应物分子转化为特定能态的产物分子的“态-态反应”之动力学特征,可涉及分子的碰撞、能量的交换、电荷的转移、中间体构型及寿命、旧键的破坏、新键的生成、产物分子的能态及其分布……全部微观的动态信息。依此可揭示化学反应的微观机理,测得反应的微观动力学参量,进而可得到宏观元反应的有关动力学参量。该学科的发展使人们对于反应动力学之本质的认识达到了更加深入的新水平。
