Make two d-orbital diagrams for each of the transition metal compounds, that show the low and high-spin states. Assume the compounds have an octahedral geometry. Determine the value of the spin-only magnetic moment for each of these configurations. Explanation of determining the value of spin-only magnetic moment would help. Ty!
