摘要
本文报导光解苯半醌自由基在不同溶液浓度、微波功率与激光能量的实验条件下电子自旋极化（ＣＩＤＥＰ）的时间演化研究。研究了在实验中出现的极化转相现象和溶液浓度对极化强度与自由基寿命的影响，并对实验结果进行了讨论。
Abstract In this paper, we present an experimental investigation on the time evolution of CIDEP of the photolyzed PBQH in ethylene glycol under different varies conditions of the concentrations, the microwave power and the laser energy. The phase change of the polarization of PBQH in ethylene glycol was observed, the concentration dependence of the polarization and the radical lifetimes was Studied, and the experimental dsta was diffused
