## Abstract The known lone pair orientation effect of an α‐nitrogen atom on ^1^__J__(C,C) couplings was studied using the natural __J__ coupling (NJC) dissection method for the Fermi contact (FC) term. This dissection was performed at the DFT‐B3LYP level using three different basis sets. It was ver
