## Abstract Herein, a series of separate dynamic ^1^H NMR effects are reported at different temperatures within a particular enaminoester involving a phenanthridine. These effects are attributed to restricted rotation around the two single bonds such as carbon–carbon (H~a~CCH~b~) and nitrogen–car
