Here’s a longer sketch of what Paul’s comment is describing. In the absence of spin–orbit coupling (SOC), the available states have well-defined spin and orbital […]

Why is manganese(II) colored although the transition should be spin-forbidden?
Selection rules The intensity of the transition from a state to a state is governed by the transition dipole moment (strictly, it is proportional to […]
Dynamic versus static electronic correlation
In quantum chemistry, when a nomenclature in which one distinguishes between “static” and “dynamic” correlation is used, “correlation” referrers to all the deficiencies of the […]
