## Abstract The major protonation sites of six cardiotonic isomeric 2βarylβ__n__βmethoxyβ1__H__βimidazo[4,5β__b__]β and β[4,5β__c__]βpyridines (n = 4β7) were determined by ^1^H and ^13^C NMR methods. All the 1__H__βimidazo[4,5βc]pyridines and the 7βmethoxy derivative of sulmazole were found to prot

## Abstract 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__βaminonitropyridines were found to gi
