The presence of two symmetry‐independent molecules in the unit cell ‐not E / Z isomerism in the crystal‐is responsible for the existence of two N ‐methyl signals in the solid‐state 13 C‐NMR spectrum of the thioamide 1. Even small conformational differences in the molecule in the solid state have a considerable effect on the chemical shift.
