Charge transfer transition

Energies of some optical transitions and the charge transfer transition are calculated based on the transition state theory .

用过渡态理论计算了部分光学跃迁和电荷转移跃迁的能量。

The colorations of ruby , sapphire , and emerald result from the d-d electron transition and charge transfer transition of transition metal ions such as chromium , iron , titanium etc.

红宝石、蓝宝石、翡翠的呈色是过渡金属离子（如铬、铁、钛等）d-d电子跃迁和电荷转移跃迁等因素共同作用的结果。
