"WebApr 17, 2024 · The paper goes on to say that because the d-orbital spin-splitting energy is stronger (i.e. larger) than the weak (i.e. small) crystal field splitting energy ( Δ 0 ), the system is said to be in the "high-spin state". This would make sense since high-spin states are sometimes characterized as having a small Δ 0, for example, in the Wikipedia ... " - Spin splitting of 1-methoxypropane
