===== Detection of the Phosphapropynylidyne Radical, CCP, toward IRC +10216 =====

The phosphapropynylidyne radical, CCP, has been detected in five lines of four rotational transitions in the 3 and 2 mm regions:\\
D. T. Halfen, D. J. Clouthier, and L. M. Ziurys,\\
**[[https://doi.org/10.1086/588024|Detection of the CCP Radical (X <sup>2</sup>Π<sub>r</sub>) in IRC +10216: A New Interstellar Phosphorus-containing Species]]**\\
//Astrophys. J.// **677**, L101–L104 (2008).\\
The //e// λ-doubling component is overlapped by stronger featueres for the first three transitions; the //f// component seems to be unaffected for all four transitions.
