Spectroscopic properties of Pr (III) and Nd (III)-mono nucleosides and nucleotides in aquated organic solvents have been investigated through absorption difference and comparative absorption spectroscopy involving 4f-4f transitions. Absorption intensity analysis, has shown that minor coordination changes in structure and chemical make-up of these structurally related ligands induced substantial changes in the intensities of 4f-4f bands and their perturbation has been reflected through oscillator strength, Judd-Ofelt intensity parameters (T(lambda); lambda = 2, 4, 6). The results show that different nucleosides and nucleotides bind Pr (III)/Nd (III) with different degrees of relative affinities.
通过涉及4f-4f跃迁的吸收差异和比较吸收光谱，研究了Pr(III)和Nd(III) - 单核核苷及核苷酸在水合有机溶剂中的光谱性质。吸收强度分析表明，这些结构相关配体在结构和化学组成上的微小配位变化会引起4f-4f能带强度的显著变化，并且其微扰已通过振子强度、贾德 - 奥费尔特强度参数（T(λ); λ = 2, 4, 6）反映出来。结果表明，不同的核苷和核苷酸以不同程度的相对亲和力与Pr(III)/Nd(III)结合。
