## Abstract The ^1^H, ^13^C and ^15^N NMR studies have shown that the __E__ and __Z__ isomers of pyrrole‐2‐carbaldehyde oxime adopt preferable conformation with the __syn__ orientation of the oxime group with respect to the pyrrole ring. The __syn__ conformation of __E__ and __Z__ isomers of pyrrol
