## Abstract The NMR variable temperature behaviour of __N__‐aroyl‐ and __N__‐thioaroyl‐__N__′‐piperonylpiperazines was investigated. The largest chemical shift separation between the exchanging methylene groups, and the highest energy barrier, is found for the thioamide compounds. Results from semi

## Abstract The 251 MHz ^1^H and the natural‐abundance 63.1 MHz ^13^C NMR spectra of __N__,__N__'‐dimethylimidazolidine have been measured from −50 to −170°C. Below about −140°C. nitrogen inversion in the compound becomes slow on the NMR time scale and both the ^1^H and the ^13^C spectra indicate t
