===== The Tentative Detection of Silylidyne ===== The tentative identification of silylidyne, SiH, toward Orion KL was reported by\\ P. Schilke, D. J. Benford, T. R. Hunter, D. C. Lis, and T. G. Philips,\\ **[[https://doi.org/10.1086/318951|A Line Survey of Orion-KL from 607 to 725 GHz]]**\\ //Astrophys. J. Suppl. Ser.// **132**, 281–364 (2001).\\ The two λ components of the //J// = 1.5 – 0.5 transition pertaining to the energetically lower lying Π1/2 spin-state near 624.9 and 627.7 GHz were detected. However, they were at least partially overlapped. As the source is rather line rich, the detection was viewed as tentative. ---- Contributor(s): H. S. P. Müller; 06, 2006 ----
