The naphthalene molecule has a structure that corre- sponds to two benzene molecules fused together: H H | H. H H H The 7-electrons in this molecule are delocalized over the entire molecule. The wavelength of maximum absorption in the UV-visible part of the spectrum in benzene is 255 nm. Is the corresponding wavelength shorter or longer than 255 nm for naphthalene?
