Solutions of potassium permanganate have a very intense purple color. For the MnO4 ion, € = 2200 M-1cm-1. This is in between what I told you a Td complex typically has for 8 in d-d transitions and what a charge transfer transition € usually is. Figure out which this is based on the oxidation state and d electron count for the complex. Sketch a molecular orbital diagram that shows what electronic transition the absorbance corresponds to.
