a) Calculate the rela- tive energies as a func- tion of Δo and P for high-spin and low-spin complexes of Fe (II) and Co(II) . (b) Calculate the CFSE in kJmol-1 for an [Ti(H2o)6]3+ octahedral complex for which d – dtransition is the single broad absor- ption peak with a max- imum at 20300 cm-1. Draw thesplitting energy diagram also. (Given that 1 kJmol-1 = 83.7 cm-1) .
