===== 2,3-Butadienenitrile, CH2CCHCN, in Space =====

2,3-Butadienenitrile, CH<sub>2</sub>CCHCN, aka cyanoallene, has been detected with the 100m Greenbank telescope toward TMC-1:\\
F. J. Lovas, A. J. Remijan, J. M. Hollis, P. R. Jewell, and L. E. Snyder,\\
**[[https://doi.org/10.1086/500431|Hyperfine Structure Identification of Interstellar Cyanoallene toward TMC-1]]**\\
//Astrophys. J.// **637**, L37–L40 (2006).\\
As the number of four observed rotational transitions is somewhat small, the (partial) resolution of the <sup>14</sup>N hyperfine structure is a decisive aspect in securing the detection.
