摘　　要：多光子过程的偏振特性可以用来标识电子态及振动结构的对称性.计算了几种简并三光子跃迁张量的理论偏振比值,还测量了乙苯的三光子共振偏振电离谱.经过偏振分析表明,产生跃迁的高电子激发态对称性为A″,并获得了它的振动结构.The polarized characteristic of multiphoton process can be used to assign the symmetries of electronic states and vibrational structures. In this paper the polarizing ratios of some kinds of degenerate three-photon transitional tensors are calculated. Besides, the three-photon resonant polarizing ioniza-tion spectra of ethylbenzene are measured. The highly excited electronic state which is responsible for the transition is referred as A' and the vibrational structures of this electronic state are also obtained.
