## Abstract The IR, ^1^H and ^13^C NMR spectra of six esters of 1‐aryl‐4‐methyl‐3‐ and 5‐pyrazolecarboxylic acids are reported. On the basis of their spectra the 3‐ or 5‐position of the substituent in such structural isomeric pairs can be established without recourse to the spectrum of the other me
