Abstract

The NMR spectra of a series of heterocyclic compounds analogous to anthracene have been investigated at 220 and 60 MHz. Correlations have been made with molecular geometry and parameters calculated from semi‐empirical MO theory. For planar molecules, the chemical shift of the proton ortho to the heteroatom is linear with respect to the electron density on the heteroatom, but otherwise chemical shifts are independent of electron density. Planarity of the molecules is also a factor in some of the coupling constants.

## 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 Pyridine, methylpyridines, quinoline and isoquinoline have been labelled with deuterium using pre‐reduced platinum dioxide (PtO~2~Β·2H~2~O) and heavy water. Their ^2^H chemical shifts from monodeuteriated TMS have been assigned. The extent of the labelling has been determined directly by
