What coordination complexes have low intensity peaks in the UV-Vis spectrum
Accepted Answer
Coordination complexes with low intensity peaks in the UV-Vis spectrum typically have d-d transitions that are Laporte forbidden. This occurs when the transition involves a change in the symmetry of the complex. For example, complexes with a center of symmetry or tetrahedral geometry often exhibit low intensity peaks. Additionally, complexes with high spin configurations may have weaker d-d transitions due to the larger energy difference between the d orbitals.
