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. … WebCFSE Calculation:Crystal Field Theory, Pairing Energy, High-Low Spin Complex, Spectrochemical Series SHYAM SIR'S CHEMISTRY CLASS 4.2K views 2 years ago ALEKS - Drawing the MO energy...

That is, … WebSep 5, 2024 · To see that this makes sense, you can think about crystal field splitting as an electrostatics problem. The orbital has to pay an energy penalty if it points towards another ion with other electrons present. Hence the orbitals that point "between" nearby ligands have the lowest energy.

WebCrystal field theory treats interactions between the electrons on the metal and the ligands as a simple electrostatic effect.
