跃迁偶极矩

跃迁偶极矩 $\scriptstyle{\mathbf{d}_{nm}}$ ，在初态 $\scriptstyle{m}$ 与末态 $\scriptstyle{n}$ 间的跃迁过程里代表了两个态间跃迁的电偶极矩。一般，跃迁偶极矩是一个含相因子的复矢量。它的方向代表跃迁的极性方向，决定了系统如何与给定极性的的电磁场间的相互作用，它的振幅平方代表了由于系统内电荷分布导致的相互作用强度。跃迁偶极矩的SI unit为库伦-米（Cm）；更为方便的单位为德拜（D）。

In general the transition dipole moment is a complex vector quantity that includes the phase factors associated with the two states. Its direction gives the polarization of the transition, which determines how the system will interact with an electromagnetic wave of a given polarization, while the square of the magnitude gives the strength of the interaction due to the distribution of charge within the system. The SI unit of the transition dipole moment is the Coulomb-meter (Cm); a more conveniently sized unit is the Debye (D).
