Spectral Characteristics of the Benzene Ring - presentation
15-4. The UV-visible spectrum of benzene reveals its electronic structure.. The energy gap between bonding and antibonding orbitals is greater in benzene than for acyclic trienes.. The UV spectra of benzene shows absorbances at smaller wavelengths (higher energy) than does the spectra of 1,3,5-hexatriene:.
