NMR Studies of a Series of Aliphatic Nitroxide Radicals

Abstract

We have examined the NMR and ESR spectra of a series of aliphatic nitroxide radicals. Isotropic coupling constants were calculated from the shifts of the NMR lines. The NMR shifts were investigated as a function of solvent and temperature. Coupling constants determined from NMR spectra were used to calculate ESR spectra. The experimental and theoretical ESR spectra were in good agreement.
