Vibrational spectra of 2‐cyanothiophene in the solid state reveal that the crystals are ordered below the freezing point and have an orthorhombic C 2v unit cell. Intermolecular forces between the two molecules occupying the Bravais unit are not strong enough to promote the separation of all the Davidov doublets of the phonon states.
