摘　　要：在无机化学中,尤其在过渡金属元素配合物中经常会遇到各种各样颜色的无机化合物。具有dx(x=1至9)结构的过渡金属配合物受到光照时,d轨道跃迁,发生d-d跃迁。化合物吸收可见光还可以发生电子从一个原子到另一个原子的跃迁而产生荷移吸收带发生电荷跃迁。酸根和固体化合物的颜色就与电荷跃迁有关。此外,离子极化作用也可以使物质具有颜色。对无机化合物显色规律、原因作了详细的总结,并对其显色机理做了深刻的探讨。In inorganic chemistry,particularly in the transition metal complexes of color often face all sorts of inorganic compounds. With dx （x = 1-9） structure of the transition metal complexes are light, d track transitions, in d-d transitions. Visible light absorbing compounds can also occur from one electronic atom to another atom arising from the transition charge transfer absorption bands in charge transitions. Dianion and solid compounds on the color transitions and the charge. In addition, the role o~ ionic polarization can also make material with color. In this paper, a deep study to the color of inorganic compounds ,the reasons for the summary detail, and its color mechanism.
