===== SiCN and SiNC in IRC+10216 ===== Cyanosilylidyne was identified in spectra recorded toward IRC+10216 by\\ M. Guélin, S. Muller, J. Cernicharo, A. J. Apponi, M. C. McCarthy, C. A. Gottlieb, and P. Thaddeus,\\ **[[https://ui.adsabs.harvard.edu/cgi-bin/nph-bib_query?bibcode=2000A%26A...363L...9G|Astronomical detection of the free radical SiCN]]**\\ //Astron. Astrophys.// **363**, L9–L12 (2000). According to //ab initio// calcultions, the isocyanosilylidyne isomer has a thermodynamic stability very similar to that of SiCN, but a slightly smaller dipole moment. Therefore, its reported detection was only a matter of time:\\ M. Guélin, S. Muller, J. Cernicharo, M. C. McCarthy, and P.
