My currently primitive understanding of metal complexes is that the d orbital splitting depends on:
- Identity of central ion
- Charge density of ligand
- Geometry of complex ion
- oxidation number of transition metal
However, I was looking for a continuous variable that could alter the splitting of the d orbitals, hence produce a change in wavelength of light transmitted.
Could the presence of different concentrations of non-chelating ions in the solution, or the temperature of the solution itself, have an effect on the d orbital splitting?
