Proton nuclear magnetic resonance spectra of pyridines

Technical Report ·
OSTI ID:6913119
; ;

The proton NMR spectra of 32 pyridines in two solvents carbon tetrachloride and benzen-d6, are presented. The chemical-shift and differential-shift values are correlated with the substitutent position and with the solvent media. The ring protons and the protons on alkyl substituents are tabulated. The paramagnetic shift of the protons adjacent to the nitrogen is discussed, and a proposed structure for the pyridine-benzene complex that is consistent with the observed anomalous paramagnetic shift is presented. The utility of the data in the identification of pyridine compounds found in shale-oil naphtha is demonstrated.
