The 13 C NMR spectra of some 1‐( N , N ‐diaroyl)amino‐1,2,3‐triazole derivatives are reported. The shifts of the methyl carbons attached to the triazole ring and those of C‐4 and C‐5 of the ring were used to distinguish between 4,5‐unsymmetrically substituted derivatives. The location of a methyl group on the 4‐or 5‐position of the ring can be also deduced from the 1 J CH 3 value. A complete assignment of the aroyl carbons of the imide moiety is given.
