According to crystal field theory, the interaction between a transition metal and ligands arises from the attraction between the positively charged metal cation and the negative charge on the non-bonding electrons of the ligand. The theory is developed by considering energy changes of the five degenerate d-orbitals upon being surrounded by an array of point charges consisting of the ligands. …

When white light falls on the compound, an electron makes a transition into a higher state thus absorbing a particular wavelength of light. The rest of the light is reflected. new york daily times newspaperWebyellow. Blue (~450 nm) is shorter wavelength light than yellow (~580 nm) It makes sense for the complex with stronger field ligands to absorb a shorter wavelength of light than the complex with one weaker field ligand, because it has a greater crystal field splitting energy.
