ELECTRONIC-SPECTRA OF NITROBENZENE DERIVATIVES

The gas and solution phase u.v. spectra of some nitrobenzene derivatives with substituents of different electron-donating power were analysed in terms of locally excited states and intramolecular charge transfer configurations in the MIM and PPP approximations. The spectral behaviour of the examined compounds is defined by the different electron-donating power of the substituents and by the degree of mixing of the excited states, following the substitution position. © 1979.
