Then we introduce the famous Fermi’s golden rule from the time-dependent perturbation theory. Applying this rule, we discuss the light absorption and emission, and obtain the physical parameters of transition possibility, transition electronic dipole moment and oscillator strength et al.
第二节介绍用量子化学中的含时微扰理论处理电子跃迁的方法,介绍了著名的费米黄金规则,并用该规则讨论了光的吸收和发射,得到了态-态间的跃迁几率、跃迁电偶极距以及振子强度等表征电子激发特征的物理量。
