## Abstract Proton coupled carbon‐13 NMR spectra of eleven mono‐, di‐ and trimethylpyridines were analysed on a first order basis. The long range ^13^C^1^H coupling constants are similar to those observed for pyridine and cyanopyridines.

## Abstract One bond and long range ^13^C^1^H coupling constants for some methoxy‐, amino‐ and hydroxypyridines are described. An unambiguous assignment of carbon‐13 resonances is carried out based on the analysis of the fine splitting caused by long range couplings. __J__ values for compounds oth
