14 From the following spectral data, and using Tanabe- Sugano diagrams (Figure 11.7), calculate A for the following: 0 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 d. [VF]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 VC13(CH3CN)3, which has absorption bands at 694 and 467 nm. Calculate A. and B for this complex.
