NMR COUPLING OF C-13 AND F-19 WITH N-14 IN NITRO-COMPOUNDS

The 13C and 14N NMR spectra of a variety of highly nitrated aliphatic, aromatic and heterocyclic compounds were obtained. The proton decoupled 13C 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 19F spectra of some fluoronitroaliphatic compounds showed that the 19F signals were also split into the expected multiplets from coupling with the 14N of the nitro groups.
