Studies on nitroaromatic compounds. Part V. The electron spin resonance spectra of some symmetrically substituted polynitroacenaphthenes
Abstract
The e.s.r. spectra of the radical anions of 3,8-dinitroacenaphthene and 3,5,6,8-tetranitroacenaphthene have been recorded at –40°. Proton and nitrogen hyperfine coupling constants have been assigned, where possible, on the basis of McLachlan MO calculations, and the spectra have been simulated using the values for the experimental coupling constants.
