D Question 7 1 pts Why does the absorption spectrum of aqueous [TI(OH2)]* exhibit a broad band with a shoulder? O An Intervalence Charge Transfer absorption overlaps with the d-d absorption. O [TI(OH2)]3+ contains ad Ti-ion and upon light absorption, there is degeneracy in the excited state leading to a Jahn-Teller distortion. O [TI(OH)]3+ contains ad Ti-ion and therefore there are two absorptions. O [TI(OH2)]** is partly reduced to [TI(OH)]2+ in aqueous solution and two absorptions which are...
