Term symbol for d7 complexes
Accepted Answer
The term symbols for d⁷ complexes depend on the spin state (high spin or low spin) and the ligand field splitting (strong or weak field).
High Spin (Weak Field): The electrons will occupy the orbitals individually with parallel spins, leading to a total spin quantum number (S) of 3/2. The term symbol is then ⁴F (where ⁴ represents the spin multiplicity 2S+1 = 4).
Low Spin (Strong Field): The electrons will pair up in the lower energy orbitals, leading to a total spin quantum number (S) of 1/2. The term symbol is then ²D (where ² represents the spin multiplicity 2S+1 = 2).
