WebJun 6, 2016 · However, as the crystal field theory explains, the peak wavelength absorbed is equal to the splitting energy $\Delta$ between the two split energy levels of the d subshell. This is illustrated in the figure below. So the splitting of the d subshell explains the peak of the absorption spectrum. However, I’m not comprehending why the curve ... WebMay 12, 2015 · Dq was derived for quantum mechanic description of the electrostatic model of crystalline fields and is connected to the radial electron density of the d-electrons, the charge of the metal and the distance of ligands and metal. The term Dq is the product of two terms D and q and is called Differential of quanta implying the energy.

WebAccording to crystal field theory, a transition metal with no bound ligands has five d- orbitals that are degenerate, or equal in energy. Binding a ligand to the metal “splits” the d- orbitals and causes some orbitals to be higher in energy than the others. This is known as crystal field splitting 1.
