摘要
用时间分辨ＥＳＲ测出的吩噻嗪／２，２，６，６－四甲基哌啶氮氧自由基（ＴＥＭＰＯ）光诱导产生的三重态发射ＣＩＤＥＰ信号可用Ｂｌａｔｔｅｒ提出的自由基－三重态对机理来解释，由荧光光谱及脉冲激光光声微量量热实验结果直接证明了Ｂｌａｔｅｒ理论关于自由基只选择淬灭双重自旋态的自由基／三重态对中的三重态的假设．
The CIDEP signal generated in the photochemical process in phenothiazine and 2,2,6,6 tetramethyl piperidingloxyl system can be interpreted by the radical triplet piar mechanism(PTPM) prposed by Bltter. Furthermoce, the results obtained from fluorescence quenching and photoacoustic calorimetric measurements provide direct confirmation that the assumption of radical (TEMPO) only selective quenching the triplet in the doublet spin state of the radical triplet pair.
