![]() ![]() This relates to the colors seen in a coordination complex. A spectrochemical series is a list of ligands ordered by ligand 'strength', and a list of metal ions based on oxidation number, group and element. Ligands that have larger \(\Delta\)) values are considered "strong field" and will absorb higher-energy light with shorter \(\lambda\) values (ie a "blue shift"). ![]() Relating the Colors of Coordination Complexes to the Spectrochemical SeriesĪccording to the Crystal Field Theory, ligands that have smaller \(\Delta\)) values are considered "weak field" and will absorb lower-energy light with longer \(\lambda\) values (ie a "red shift"). \): Color wheel with wavelengths marked (CC BY-SA 4.0 International Tem5psu via source) ![]()
