## Abstract The potential of ^13^C NMR techniques for studies of nicotine metabolism has been investigated by acquisition and assignment of ^13^C NMR spectra of nicotine, its metabolites and some related compounds. It is shown that C‐2β€² of nicotine would be the best site for ^13^C labelling when us

## Abstract ^13^C NMR chemical shifts and ^13^Cο£Ώ^31^P couplings are reported for triphenyl phosphate and 13 alkyl derivatives. In __ortho__‐alkylated materials, it is found that the upfield Ξ³ shielding effect is only operative when the carbon atom, situated Ξ³ to the exocyclic oxygen, bears at least
