Paramagnetism in coordination complexes arises from unpaired electrons; its magnitude reflects both spin and orbital contributions. The spin-only magnetic moment (in Bohr magnetons, μB) is given by μ\_so = √(n(n+2)) μB, where n is the number of unpaired electrons. For example, a d1 or d9 ion (n=1) has μ\_so = √3 ≈ 1.73 μB. This formula assumes orbital angular momentum is __________ ________ _______ ___ ______ __________ __________ _________ _________.
