## Abstract By using digital deconvolution to improve spectral resolution, earlier NMR studies on ^15^Nโ€enriched acetamide have been revised and extended to determine the signs of the heteronuclear spinโ€spin coupling constants. ^1^__J__(^13^CO^15^N), ^2^__J__(^13^CH~3~^15^N) and ^3^__J__(C^1^H~3~^1

Non-empirical calculations using the equations-of-motion approach are reported for iJ( 15Nt5N) in hydrazine, diazene, isodiazene, the azide anion, and nitrogen. Irrespective of the single or multiple nature of the bond between the nitrogens, iJ( isNi5N) should be negative in all compounds. The only
