However, from the assumptions that the ligands are
point charges, it follows that anionic ligands should exert the greatest
splitting effect The anionic ligands actually are found at the low end
of the spectrochemical series Further, it does not take into account
the covalent character of bonding between the ligand and the central
atom These are some of the weaknesses of CFT, which are explained
by ligand field theory (LFT) and molecular orbital theory which are
beyond the scope of the present study
