Benzene may be regarded as a two-dimensional box of side about 3.5 angstroms and containing six pi electrons. Recall than any state can hold a maximum of two electrons. What wavelength of light would be required to promote an electron from the highest occupied molecular orbital (HOMO) to the lowest unoccupied molecular orbital (LUMO)?
