A unique probe designed to acquire nuclear magnetic resonance difference spectra of two samples is presented. The NMR Difference Probe contains two sample coils in a resonant circuit that switches between parallel excitation and serial acquisition to cancel common signals such as solvent peaks and i
Nitrogen NMR shieldings (\*p \ [d on the frequency scale of chemical shifts), measured by highprecision 14N NMR and bulk susceptibility corrected, of 20 nitroalkanes in dilute solutions in cyclohexane and in acetone are reported, including vic-dinitro, gem-dinitro and trinitro structures and tetrani
