利用脉冲紫外激光光激发和脉冲电子顺磁共振波谱技术研究了玻璃甲苯基体中蒽的光激发三重态。定量分析了三重态寿命、高场特征态之间的三重态弛豫率和三重态亚能级居群。高质量的数据支持前一个结论，即进入单个零场分量的激励是通过独立的通道进行的。
Photoexcited triplet states of anthracene in a glassy toluene matrix were investigated using pulsed UV-laser photoexcitation and pulsed electron paramagnetic resonance spectroscopy. The triplet lifetime, the triplet relaxation rates between the high-field eigenstates and the populations of the triplet sublevels are quantitatively analysed. High-quality data allows for supporting the former conclusion that excitations into the individual zero-field components proceed via independent channels.
