The gas-phase ion Ti2+ has a 3F ground state term. The 1D and 3P terms are 8.60 x 102 and 1.080 x 103 cm-1 higher in energy, respectively. The energy of the terms expressed in Racah parameters are given below. Use this information to (i) determine the values of B and C for Ti2+ in cm-1 energy units and (ii) determine the ratio C/B, which is normally about 4. (Hint! Remember that transition energies are associated with the difference between state energies, not the energies themselves) E(3F) = A – 8B E(3P) = A + 7B E(1D) = A – 3B + 2C
