%S and I4N NMR spectra of nine sulphnr-nitrogen compounds are reported. It is demonstrated that "N NMR gives high signal-to-noise spectra with good discrimination of chemical shifts. It is concluded that both I4N and "S NMR can make a useful contribution to the study of sulphur-nitrogen chemistry an

## Abstract Nitrogen‐15 NMR spectra of 11 ketenimines have been taken both at the natural‐abundance level of ^15^N and with the aid of ^15^N‐labeling. The nitrogen chemical shifts are substantially different from those of neutral imines and are upfield, more like those of protonated imines. The res

## Abstract The NMR spectra of a spiro oxirane (**1**) derivative of codeinone, codeine (**2**), isocodeine (**3**), 6‐methylcodeine (**4**) and 6‐methylisocodeine (**5**) were compared. NOE and double‐resonance experiments were used to confirm the conformation of **1**, and the configuration about
