The major effects of nitroxides on substrates in proton spectra is well studied, while the effect on carbon spectra has received less attention. Present knowledge relies on chemical shift differences between diamagnetic and paramagnetic solutions of the substrates to propose interactions. Changes in scalar coupling constants (JCH) would, however, provide better insight. Herein, we present a method of utilizing coupled 13C NMR spectra where differences in 1JCH coupling show alternate modes of… CONTINUE READING
