The 13 C and 14 N NMR spectra of a variety of highly nitrated aliphatic, aromatic and heterocyclic compounds were obtained. The proton decoupled 13 C peaks of the nitro‐substituted carbons in most of these compounds were split into the multiplets expected for coupling with spin 1 nuclei with negligible quadrupolar broadening. In addition, the 19 F spectra of some fluoronitroaliphatic compounds showed that the 19 F signals were also split into the expected multiplets from coupling with the 14 N of the nitro groups.
