Application of Landé Interval Rule?

01 March 2025 0 8K Report

I want to know if "Landé Interval Rule" can be applied to Co(II) weak field octahedral complexes if I know the spin-orbit coupling constant and the crystal field splitting energy. Is this rule only applied for free ions? Also, if I can apply it, where can I find the values for the total angular momentum for the different energy levels in the aforementioned complex?
