Abstract:An INDO method extended to include a contribution from the solvent by means of an effective solvent field (INDO-ESF) and based on properly optimized geometries is applied to the nitrobenzene and 1,4-dinitrobenzene radical anions. The hyperfine couplings and their solvent sensitivities are reproduced within a planar structure of the radicals. The behaviour of14N and17O splittings in derivatives with twisted nitro groups is accounted for with no difficulty.
