WebSpectrochemical series gives the arrangement of ligands in the increasing order of crystal field splitting. Weak field ligands cause less crystal field splitting. They form high spin complexes. Examples include chloride ions, fluoride ions etc. Strong field ligands cause greater crystal field splitting. They form low spin complexes.

WebApr 14, 2014 · The spectrochemical series is an ordering of relative ligand interaction strength with metal ions. It can be used to infer relative σ -donor strength, if π -interactions are not possible for those particular ligands. Examples of this type ligand with no π -interactions include N H X 3, C H X 3 X −, and H X −.
