Accurate values of i J (HH) and i J (CH) were obtained for a series of hydroxy‐and mercaptopyridines and‐pyrimidines. It is shown that the 3 J (CH) values provide a valuable criterion for differentiating aromatic from quinoidal structures, and is an easy method for determining N ‐methylation or N ‐addition sites.
