The mass spectra of some substituted thiophene‐2‐carboxanilides at 70 eV are reported. The primary degradation reaction of these compounds involves cleavage of the amide bond, followed by elimination of CO. The effect of substituents on the mass spectra are related by the Hammett equation. The correlation against σ and σ + is poor.
