We present electronic spectra in the π–π* region of a series of tris(bpy)–M(II) complex ions (bpy = 2,2′-bipyridine; M = Mn, Fe, Co, Ni, Cu, Zn) in vacuo for the first time. By applying photodissociation spectroscopy to cryogenically cooled and mass selected [MII(bpy)3]2+ ions, we obtain the intrinsic spectra of these ions at low temperature without perturbation by solvent interaction or crystal lattice
我们展示了一系列三(bpy)-M(II)复杂离子(bpy = 2,2'-联吡啶; M = Mn,Fe,Co,Ni,Cu,Zn)的π–π *区的电子光谱第一次在真空中。通过将光解离光谱应用于低温冷却和质量选择的[M II(bpy)3 ] 2+离子,我们获得了这些离子在低温下的固有光谱,而不会因溶剂相互作用或晶格移位而引起干扰。这使这些络合离子的光谱分析比冷凝相中的分析更为详细。我们通过与时间相关的密度泛函理论进行比较来解释我们的实验数据。
