It is shown that 13 1 C, H spin-spin coupling constants can be used to study heteroaromatic tautomerism. Results for the title compounds are supported by 15 N-NMR data. NMR spin-spin coupling constants between carbon-13 and protons have recently been recognized as sensitive probes for the elucidatio
