## Abstract By using digital deconvolution to improve spectral resolution, earlier NMR studies on ^15^N‐enriched acetamide have been revised and extended to determine the signs of the heteronuclear spin‐spin coupling constants. ^1^__J__(^13^CO^15^N), ^2^__J__(^13^CH~3~^15^N) and ^3^__J__(C^1^H~3~^1
## Abstract The details of two‐dimensional ^13^C^1^H correlated spectra have provided information about the relative signs of __J__(C, F) and __J__(F, H) for several molecules in which C, F and H are mutually coupled. Unlike signs are found for __J__(C, F) and __J__(F, H) when the coupling pathway
