Abstract
Abstract The ESR spectra of the title radical have been obtained in various solvents, and the assignments have been made. It is found that the solvent effects on the hyperfine coupling constants(hfc) for hydrogens on the benzene ring were small, while the nitrogen hfc (aN(1)) remarkably increased in polar solvents. The solvent dependence of the nitrogen hfc has been explained in terms of a substantial contribution of dipolar resonance structures through the N–O bond.
