Abstract

The carbon‐13 NMR spectra of some N‐(2‐ or 4‐nitrophenyl) tertiary amines and their corresponding N‐oxides have been analysed. These N‐oxides undergo thermal rearrangement to O‐arylhydroxylamines, for which the ^13^C NMR spectral assignments were also carried out. The N‐oxidation effect on the aromatic and aliphatic fragments is calculated.

## Abstract Carbon‐13 NMR chemical shifts and ^1^__J__(CH), ^2^__J__(CH) and ^3^__J__(CH) coupling constants of selected saturated nitrogen heterocyclic molecules containing the acetylenic moiety have been determined. These NMR parameters have also been determined for the corresponding __N__‐oxides
