钯—氨基酸络合物的光声光谱研究Pd（L-his）Cl₂∙H₂O和Pd（Gly）₂∙2H₂O

摘要: 本文制备了Pd（L-his）Cl₂∙H₂O和Pd（Gly）₂∙2H₂O络合物晶体。在280-780nm范田内测定并解释了络合物晶体的室温光声光谱。对络合物的结构化学特性进行了讨论,同时根据络合物光声位相谱研究了二价钯络合物中钯离子的能级寿命以及激发电子非辐射去激励过程。计算了二价钯离子在D_4h对称性下的能级寿命。在不同的配体环境中其能级寿命是不同的。

Abstract: In this work, thc crystals of Pd（L-his）Cl₂∙H₂O and Pd（Gly）₂∙2H₂O complexes are synthesized. And the room temperature photoacoustic spectra of these complexes are determined and explained in the region of 280-780nm. The characterizations of structural chemistry of these two complexes arc discussed. Then, thc energy levels life and the excitation electron nonradiativc relaxation channel of Pd（Ⅱ） ion in complex system are studied by the photoacoustic phase spectra of complexes. The energy levels life of Pd（Ⅱ） ion in D_4h group are calculated, the energy levels life will be different for the different coordinated ligands.
