The electronic structures and substituent effects of o-, m-, and p-chloronitrobenzene and bromonitrobenzene have been studied by ultraviolet photoelectron spectroscopy (UPS). It was found that the o-isomer possesses particular electronic properties. This characteristic depends on the conjugation between the benzene ring π orbital and the nitro group π orbital and the interaction of the halogen and nitro groups in the adjacent position.
