Starting material was [(Me5dien)CoCl2] and reacted with SCN to produce [(Me5dien)Co(SCN)2]. Using the two graphs given below how does the shifts in lamdamax for the observed peaks support your notion that Cl has been replaced with N? [(Me5dien)CoCl2] Peak A: 531.8 nm, 0.722 Abs Peak B: 609.7 nm, 0.666 Abs [(Me5dien)Co(SCN)2] Peak A: 510.2 nm, 0.357 Abs Peak B: 608.10 nm, 0.401 Abs
