摘要
本文利用脉冲激光光声微量量热方法，以蒽为标准化合物，尝试求几种有机化合物，如吖啶、二苯酮、吩噻嗪及菲的三线态形成量子产率ΦＴ。结果发现吖啶的ΦＴ值与文献［１］吻合得很好；由于实验所用传感器时间响应的限制，所求其他三种化合物的ΦＴ值与文献值有较大的偏差，为此，利用解卷积方法，扣除传感器的响应后，即可求得较满意的ΦＴ值。
The quantum yields of triplet state formation (Φ T ) of acridine,benzophenone.phenothiazine and phenanthrene were measured with anthracene as calibrating compound by the means of pulsed laser photoacoustic calorimetry.It was found that Φ T of these compounds were not in accordance with the literature results except acridine due to slow response of PZT transducer.But the better results could be obtained by using deconvolution method to eliminate the effect of respose of the transducer.
