The spectrochemical series was first proposed in 1938 based on the results of absorption spectra of cobalt complexes. A partial spectrochemical series listing of ligands from small Δ to large Δ is given below. (For a table, see the ligand page.)

WebStrong-field ligands, such as CN − and CO, increase the Δ splitting and are more likely to be low-spin. Weak-field ligands, such as I − and Br − cause a smaller Δ splitting and are more likely to be high-spin. Some octahedral complexes exhibit spin crossover, where the high and low spin states exist is dynamic equilibrium. WebFeb 13, 2014 · Oxalate ion (C 2 O 4 2-) is a weak field ligand.It causes only a small splitting of energy levels due to which it is energetically more favourable for the electrons to occupy the upper e g level rather than pairing up in the t 2g level. Example: K 3 [Fe(oxalate) 3] 3H 2 O is a high spin complex with five d electrons distributed as t 2g 3 e g 2. WebLigands that give rise to large differences between the energies of the t 2g and e g orbitals are called strong-field ligands.Those at the opposite extreme are known as weak-field ligands.. Because they result from studies of the absorption spectra of transition-metal complexes, these generalizations are known as the spectrochemical series.The range of … homestead exemption harris county ga
