o-Xylene sensitized biacetyl fluorescence and phosphorescence have been investigated and photosensitized fluorescence and phosphorescence lifetimes of biacetyl in the vapor phase have been determined. Attempts to detect the triplet of biacetyl by its absorption spectrum were unsuccessful, primarily due to, it is believed, the low extinction coefficients of the triplet, and the low triplet concentrations produced by the optical pumping device at room temperature.
对邻二甲苯敏化的双乙酰荧光和磷光进行了研究,并测定了双乙酰在气相中的光敏荧光和磷光寿命。试图通过双乙酰的吸收光谱检测其三重态,但未成功,据信这主要是由于三重态的消光系数较低,以及光泵浦装置在室温下产生的三重态浓度较低。
