摘要
在正常状态下镧系(Ln^(3+))4f壳层电子的跃迁是被禁止的。但是在配位场的作用下f-f跃迁则会发生,这将导致镧系水合离子光谱中狭窄的光吸收率强度相应的增大。此种现象称之为超灵敏跃迁(Hypersensitive transition)。
The complex formation of lanthanides(Nd^(3+),Ho^(3+)and Er^(3+))-citrie acid(H_(3)Cit)-acetylacetone(HA)has been studied by spectrophotometry.It was found that the lanthani-des combine with H_(3)Cit and HA at the ratio 1:1:1.From this datum obtained,the oscillator strength P of Ln^(3+)in solutions of both binary and ternary compounds has been calculated and the ralated general rule,that the oscillator strength P follows formulated.
