晶体场中铁族离子的轨道分裂

THE ORBIT SPLITTING OF IONS IN IRON FAMILY IN CRYSTAL FIELD

用群论和量子力学的方法，推断铁族离子的３ｄ轨道在不同对称性的晶体场中的分裂，进而讨论３ｄ电子在分裂轨道上的分布以及分裂能．再从３ｄ轨道的分裂出发，由量子力学计算有关能级和跃迁的吸收谱的结果，可得到矿物某些性质的微观机制的信息，如矿物颜色的多色性的原因等。

With the method of group theory and qucutum mechanis,it can be inferred that the 3d orbit of ions in iron famlly will be splitting in different symmetric crystal field.Thus it leads to a further discussion of the distribution and splitting and splitting energy of the 3d electrons on their splitting orbit.Based on the above reasoning,as a result of its energy levels and transitions,calculated by means of qucutum mechanis,microme chanism informations of certainminerals can be learned such as the causes of mineral’s various colours and so on.
