摘要： 本文报道了一套适用于液相体系的高灵敏度脉冲激光光声量热装置的建立。用此仪器对香豆素激光染料C428, C47和C120的无辐射过程进行了研究, 测得它们在无水乙醇中的无辐射跃迁量子产额分别为0.50, 0.47和0.38。

Abstract: A high sensitive pulsed laser photoacoustic calorimeter for liquid sample has been set up in our laboratory. Using this equipment, the radiationless quantum yields of three coumarins in absolute ethanol were measured to be 0.50±0.02, 0.47±0.02, and 0.38±0.02 for C428, C47 and C120, respectively.
