The Electron Spin Resonance spectra of radicals prepared from compounds derived from N-aryl substituted hydroxylamines have been studied. The preparative details together with certain analytical evidence in favour of the proposed structures are given. The coupling constants have been obtained and show that, in one series of compounds, hyperconjugative coupling between remote parts of the molecule takes place. A steric effect has been observed from radicals derived from N - ortho -methyIphenylhydroxylamines while the effect of other ring substituents has also been considered. The effect of the second N-substituent on the coupling constants has been studied and is seen to have little effect on the relative spin densities of the aromatic proton and nitroxide nitrogen nuclei. After an introductory section and one devoted to the basic theory, a section is included which describes the construction and use of a spectrometer.
