## 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 Cβ2β² of nicotine would be the best site for ^13^C labelling when us
The =C chemical shifts of a series of isoflavones having hydroxy, acetoxy, methoxy and methylenedioxy substituents are compared. Some general relationships between substitution patterns and chemical shifts, useful for the identitication of naturally occurring isoflavones, are outlined.
