A new method for obtaining 1H NMR structural information on nitroxide spin labels through reduction to hydroxylamine by radiolysis of their methanolic solutions
Abstract
A preliminary description of a convenient method for the reduction of nitroxide spin labels by a radiolysis technique is described; the main advantage of this procedure is the ease with which nitroxides are converted to the corresponding non-paramagnetic hydroxylamines, the 1H NMR spectra of these hydroxylamines gives structural information on the parent spin labels.
