Term used to describe scalar coupling over a single bond? I know that coupling on NMR over two bonds is referred to as geminal coupling and over three bonds is referred to as vicinal coupling. However is there a term for coupling over one bond (such as a carbon-13 bonded to a fluorine?
I've never heard a special term but you can describe it as $^1 J$ or $^1 J_{CF}$ coupling using the systematic nomenclature.
