络合物的紫外可见光谱乃络合物中过渡金属离子的 d 电子产生 d-d 跃迁的结果,这是人们所熟知的事实。然而,d-d 跃迁却属于不符合选择定则的所谓禁阻跃迁。那么,为何禁阻跃迁能产生光谱?难道,在络合物光谱中允许跃迁和禁阻跃迁没有区别?亦或络合物中 d-d 跃
It is well known that UV-Vis spectra of complexes are the result of d-electron d-d transitions of transition metal ions in complexes. However, d-d transitions are so-called forbidden transitions that do not meet the selection criteria. So why banned transitions produce spectra? Is there no difference in the allowed and forbidden transitions in the complex spectra? Or in complexes d-d
