Molecules that are brightly colored have a small energygap between filled and empty electronic states (theHOMO-LUMO gap; see Exercise 9.104). Sometimes youcan visually tell which HOMO-LUMO gap is larger for onemolecule than another. Suppose you have samples of twocrystalline powders—one is white, and one is green. Whichone has the larger HOMO-LUMO gap?
