WebSep 7, 2024 · However, as a general rule of thumb, most 3d metal complexes are high-spin. If you return to the fundamental criterion for high- vs low-spin, i.e. the relative magnitudes of Δ o and the pairing energy, you will find that for many 3d metals, Δ o is small due to the poor overlap of the 3d orbitals with ligand orbitals.

WebMay 1, 2016 · Spin-orbit coupling The problems arise because the total states are not separable into spin and spatial components. This occurs because both electron spin, as well as orbital angular momentum, are both angular momenta. They therefore interact with each other, and this is the spin-orbit coupling spoken of. WebThe high spin complex is the compound with the greatest number of unpaired electrons. There are fewer unpaired electrons in the low spin complex.
