Abstract

The ^1^H NMR spectra of the protonated and unprotonated forms of cis‐ and trans‐N‐methylhexahydroisoindoline, of 1,3,3,4,4‐pentamethylpyrrolidine and of 1,3,3‐trimethylpyrrolidine were analyzed. The coupling constants between the NH⊕ and the CH protons α to the nitrogen allowed the study of the conformation of the cyclic systems in pseudorotation.
