The 1 H NMR spectra of 26 nitrated aminopyridines were measured and interpreted. Chemical shift assignments were based on existing chemical shift rules for substituted pyridines and spectral comparison with compounds of similar structure. Some o ‐aminonitropyridines were found to give a splitting of the amino signals due to intermolecular hydrogen bonding; steric hindrance is shown to influence this bonding.
