The dipole moments of several asymmetrically 4,5‐substituted 1‐(α‐aroyloxyarilideneamino)‐1,2,3‐triazoles, produced by oxidation of bis‐aroylhydrazones of α‐dicarbonyl compounds, were measured in benzene solution. The structure and the probable conformation of each of these compounds was determined by comparing their experimental and theoretical dipole moments. It has been found that when one of the substituents R 1 or R 2 is an aryl group, it is located at the 4‐position of the triazole ring. Considering the conformation of the ester‐imino function, it has been found to be the same as that of symmetrically substituted derivatives.
