| The '''cyano radical''' is a [[Radical (chemistry)|radical]] with molecular formula ·CN. The cyano radical was one of the first detected molecules in the [[interstellar medium]] and has helped the field of [[astrochemistry]] a great deal. The first discovery was performed with a coude spectrograph which was made famous and credible due to this detection. ·CN has been observed in both diffuse clouds and dense clouds.<ref name="Comparative">{{Cite journal| url=http://www.aanda.org/index.php?option=article&access=bibcode&bibcode=2001A%2526A...370..576LPDF| format=PDF| author1=Liszt, H. | author2=Lucas, R.| title=Comparative chemistry of difuse clouds| publisher=[[Astronomy and Astrophysics]] |year=2001 | volume=370| issue=2| pages= 1–11| accessdate=4 August 2009| doi=10.1051/0004-6361:20010260| journal=Astronomy and Astrophysics | bibcode=2001A&A...370..576L|arxiv = astro-ph/0103247 }}</ref> Usually, CN is detected in regions with [[hydrogen cyanide]], [[hydrogen isocyanide]], and [[HCNH+|HCHN<sup>+</sup>]] since it is also used In the creation and destruction of these molecules.

| The cyano radical exists as a resonance structure, the form depicted with the unpaired electron on the carbon, is in fact a minor contributor, the major contributor is the isocyano radical. In the isocyano radical, the electron is associated with the nitrogen, resulting in a charge separation similar to [[carbon monoxide]].
| |
| | |
| ·CN has a radical on the carbon and a [[Molecular dipole moment|dipole moment]] of 1.45 Debye. ·CN has a <sup>2</sup>Σ ground electronic state. The [[selection rule]]s are:
| |
| | |
| :<math>N + S = J</math> | |
| | |
| :<math>J + I = F</math>
| |
| | |
| Where ''N'' is the [[angular momentum]], ''S'' is the electric spin, and ''I'' is the nitrogen nuclear spin, which is always 1.<ref>{{Cite journal | title=The millimeter and submillimeter spectrum of ·CN in its first four vibrational states |last1=Skatrud| first1=David D.| first2=Frank C.| last2=De Lucia| first3=Geoffrey A.| last3=Blake| first4=K.
