I ′ < Br < NH 3 < en < [NCS] ′ < Cl ′ < F ′ < [OH] ∗ < … WebMar 31, 2024 · For example, the oxidation state and the strength of the ligands determine splitting; the higher the oxidation state or the stronger the ligand, the larger the splitting. Ligands are classified as strong or weak based on the spectrochemical series: I- < Br- < Cl- < SCN- < F- < OH- < ox2-< ONO- < H2O < SCN- < EDTA4- < NH3 < en < NO2- < CN-
WebStrong-field ligands (EDTA → CN-) absorb high-energy light (i.e. blue-violet) and appear red-yellow in color. Complexes with ligands that are between strong and weak on the spectrochemical series, like ammonia, can adopt either a weak- or strong-field geometry. The color-ligand relationship is the rationale for the name "spectrochemical series". WebTwo Spectrochemical Series Purpose of the Experiment Both ligands and metals have an effect on the Crystal Field splitting parameter, so. In this experiment, you will generate two spectrochemical series. The first will be a ligand series, using octahedral (or pseudo- octahedral) copper (II) complexes.
