## 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 βˆ’50 to βˆ’170Β°C. Below about βˆ’140Β°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
