Pairing energy chemistry
Webpairing energy (P) depend on the identity of both metal and ligands and it is not possible to specify a point in the spectrochemical series at which a complex changes from high spin to low spin. e.g. d4 elements : 1.) High spin: three 3d electrons occupy separate t2g and one electron occupies one of the eg orbitals -> pairing penalty avoided Web"Pairing energy, P, is the energy required to place two electrons in the same orbital. If the crystal field splitting (Δ) is small because of weak-bonding ligands, then the pairing …
