Suppose the synthesized Nickel (II) complexes are paramagnetic (3.68 B.M.) with a tetrahedral geometry and they showed 4 absorptions band: two intraligand, a charge transfer (470nm) and 3T1(F) to 3A2(F) (680 nm). This last band are in greater energy than 3T1(F) to 3T2(F) expected transition.So how to suggested an attribution of a bigger transition first than an expected lower one? Or How to interpret the correct transitions for each wavelength for Ni(II) tetrahedral complex?
