Cyclopropyl cyanide is the smallest carbon ring molecule with a cyanide group attached to it. It is mainly known by its involvement in experiments with microwave spectroscopy, rotational spectroscopy and photodissociation. In 1958, cyclopropyl cyanide was first studied for its rotational spectra, by Friend and Dailey. Additional experiment involving cyclopropyl cyanide was the determination of the molecule's dipole moment through spectroscopy experiments, by Carvalho in 1967.
