6.6: D-D transition – Color Formation (4) Copy
Physical explanation of color formation in our eyes. Geometry of 5 d suborbitals (T2g & Eg). The increase in size of Mn ion because of shielding effect by Eg suborbitals on the ligands. The transfer of electron from Eg to T2g and vice versa causing absorption of visible part of E.M spectrum forming colored compounds.
