From the following spectral data, and using Tanabe– Sugano diagrams ( Figure 11.7 ), calculate Δ_o for the following:

a. [Cr(C₂O₄)₃]^3- , which has absorption bands at 23,600 and 17,400 cm^-1 . A third band occurs well into the ultraviolet.

b. [Ti(NCS)₆]^3-, which has an asymmetric, slightly split band at 18,400 cm^-1 . (Also, suggest a reason for the splitting of this band.)

c. [Ni(en)₃]²⁺, which has three absorption bands: 11,200, 18,350, and 29,000 cm^-1 .

d. [VF₆]^3-, which has absorption bands at 14,800 and 23,250 cm-1, plus a third band in the ultraviolet. Also calculate B for this ion.

e. The complex VCl₃(CH₃CN)₃, which has absorption bands at 694 and 467 nm. Calculate Δ_o and B for this complex.
