Carbon‐13 nuclear magnetic resonance spectra of nicotine metabolites and related compounds

Abstract
The potential of 13C NMR techniques for studies of nicotine metabolism has been investigated by acquisition and assignment of 13C NMR spectra of nicotine, its metabolites and some related compounds. It is shown that C‐2′ of nicotine would be the best site for 13C labelling when using the method to gain further insight into the metabolic pathways of nicotine.
