摘　　要：介绍了近年发展起来的时间分辨 TRESR技术 ,以 3个实例介绍了用 TRESR研究光解自由基的电子自旋极化的状况 ,指出研究自旋极化可以得到关于分子激发态和自由基反应动力学等丰富的多方面信息 。The recently advanced time resolved electron spin resonance (TRESR) technique was given briefly. By three examples, the studies of the chemically induced dynamic polarization of photolysis free radicals by TRESR technique were presented. It was pointed that the rich and various information about the exsited state of molecular and the reaction dynamic of the photolysis free radicals could be obtained from the spin polarization studies, and TRESR technique is an important tool to research interaction between light and molecules
