Dipolar Character of Ligand-Centered Transitions in Transition Metal Tris-bipyridine Complexes
Stark spectra Tris-bipyridyl complexes UV spectroscopy Zn complexes
2016/5/23
The Stark spectra of bipyridine (bpy) and the metaltris(2,2'-bipyridine) complexes of Zn, Fe, Ru and Os have been measured in the ligand-centered region in the near UV. The results show that excitatio...
