本文报导C_(311)/乙醇溶液光解机理的研究.在光解前后,对香豆素C_(311)激光染料介质进行了吸收、荧光、红外和核磁共振谱的测定,实验结果表明在Nd:YAG三次谐波355nm和脉冲氙灯泵浦条件下,溶剂光解产物主要为乙酸.据此提出下列激光诱导光化学反应机理;在UV激光或脉冲氙灯泵浦条件下,溶剂中的氧由于高位三重态T_2染料分子的能量转移而被激发,并氧化香豆素分子生成隐色基. In this paper, the photolysis mechanism of C_ (311) / ethanol solution was reported. The absorption, fluorescence, infrared and nuclear magnetic resonance spectra of coumarin C_ (311) laser dye media were measured before and after photolysis. : YAG third harmonic 355nm and pulsed xenon lamp pumping conditions, the solvent photolysis products mainly acetic acid.Accordingly, the following laser-induced photochemical reaction mechanism; UV laser or pulsed xenon lamp pumping conditions, the oxygen in the solvent due to high triple State T_2 dye molecules are excited by the transfer of energy and oxidation of coumarin molecules generated leuco-based.
