## Abstract NMR spectroscopic studies are undertaken with derivatives of 2‐pyrazinecarboxylic acid. Complete and unambiguous assignment of chemical shifts (^1^H, ^13^C, ^15^N) and coupling constants (^1^H,^1^H; ^13^C,^1^H; ^15^N,^1^H) is achieved by combined application of various 1D and 2D NMR spe
