The color in KMnO4 arises from an electronic transition, but it is actually not a d-d ... When the light is reflected (or transmitted) it is missing the frequencies of the light absorbed, and so it looks pink.
Which set of quantum numbers are not possible from the following: (1) n=3, l= 2, m=0, s= -1/2 (2) n=3, l= 2, m=-2 s= -1/2 (3) n=3, l= 3, m=-3,
