✦ Synopsis

Formanilide has been investigated by free-jet millimeter-wave absorption spectroscopy. The rotational spectrum of the conformer with the formyl hydrogen anti to the phenyl group has been assigned. Several rotational transitions of the ground state have been measured for both normal and ND isotopic species. All the atoms of the peptidic group are coplanar to the ring.
