Abstract: The UV-VIS spectra of (E)-β-nitrostyrenes were measured. It was stated, by means of CNDO/S calculations, that a long-wavelength band corresponds to the electron transfer from the HOMO to LUMO level, while the short-wavelength one originates from the transitions ψHOMO-2→ ψLUMO and ψHOMO-1 → ψLUMO+1. On the basis of the energy of the former band the electron affinity of these compounds was approximated.
