| 摘 要： | 化学诱导动态电子自旋极化(CIDEP)来源于顺磁粒子在其自旋能级间的非Boltzmann分布,主要有四种形成机理即三重态机理(TM)、自由基对机理(RPM)、自旋相关自由基对机理(SCRP)、自由基-三重态对机理(RTPM).本文系统地介绍了这四种机理的概念和相应的物理和化学过程,列出了每种机理的极化强度表达式,分析了每种机理产生的CIDEP谱的典型特征并给出了代表性的实验谱线.

| Abstract: | The phenomenon of transient populations of electron spin states deviating from the Boltzmann distribution has been known as chemically induced dynamic electron polarization(CIDEP).Up to now,there are four generations known to form CIDEP on photolyzed radicals,such as triplet mechanism,radical pair mechanism,spin-correlated radical pairs and radical-triplet pair mechanism.In this review,not only the CIDEP concept,but also the photophysical and photochemical process are introduced in detail.Furthermore,the po... |
