摘要

给出了在77 K玻璃溶剂中记录的三苯和truxene的磷光光谱。它们的振动结构是在量子化学计算计算强度的基础上解释的。观测强度与模拟强度之间的一致性非常令人满意，有助于改进和完成两个盘状分子基态频率的分配。

THE PHOSPHORESCENCE SPECTRA OF TRIPHENYLENE AND TRUXENE: A COMBINED EXPERIMENTAL AND THEORETICAL INVESTIGATION OF THE VIBRONIC STRUCTURE

The phosphorescence spectra of triphenylene and truxene, recorded in glassy solvents at 77 K, are presented. Their vibronic structure is interpreted on the basis of intensities computed with the help of quantum-chemical calculations. The agreement between observed and simulated intensities is very satisfactory and contributes to improve and complete the assignment of ground state frequencies of the two disk-like molecules.
