Electron‐impact mass spectra are presented for various substituted thieno[2,3‐ b ]‐ and thieno[3,2‐ b ]‐pyridines. In particular, it is shown that chemical structures of alkylthienopyridines can be correlated (a) with their mass spectral fragmentation patterns and (b) with the proton magnetic resonance spectra of their picrate salts.
