The ground state term symbols of Fe³⁺ and Fe²⁺ in a high spin ligand system respectively are ___________.

Fe³⁺ and Fe²⁺ have d⁵ and d⁶ electronic configurations and both are in high spin ligand system. The term symbol is calculated by the formula- ^2s+1L_J For d⁵, n = 5s = n/2 = 5/2 2s+1 = 6 L = 0 = S J = (L+s) to (L-s) = 5/2 Possible term symbol for Fe³⁺ = ⁶S_5/2 Similarly, possible term symbols for Fe²⁺ = ⁵D₄, ⁵D₃, ⁵D₂, ⁵D₁, ⁵D₀
The ground state term for Fe³⁺ is ⁶S_5/2. The ground state term for Fe²⁺ is ⁵D₄.
