20.38 (a) The values of Emer for the most intense absorptions in the electronic spectra of CoCl4]- and (Co(OH).]2+ differ by a factor of about 100. Comment on this observation and state which complex you expect to exhibit the larger value of max- (b) In the electronic absorption spectrum of a solution containing V(OH))”+, two bands are observed at 17200 and 25 600 cm . No absorption for the A2, Tję(F) transition is observed. Suggest a reason for this, and assign the two observed absorptions. (c) Red crystalline (NiCl (PPh CH Ph), is diamagnetic. On heating to 387 K for 2 hours, a blue-green form of the complex is obtained, which has a magnetic moment of 3.1818 at 295 K. Suggest an explanation for these 20.40
