===== On Ethenimine in the ISM ===== The detection of ethenimine, aka ketenimine, in Sgr B2(N-LMH) has been reported very recently:\\ F. J. Lovas, J. M. Hollis, A. R. Remijan,and P. R. Jewell,\\ **[[https://doi.org/10.1086/506324|Detection of Ketenimine (CH2CNH) in Sgr B2(N) Hot Cores]]**\\ //Astrophys. J.// **645**, L137–L140 (2006).\\ Three lines have been detected thus far with the 100 m GBT of which one line at 4.9 GHz probably shows partially resolved hyperfine structure. The proposed single state temperature of 65 K appears to be peculiar and may indicate non-thermal population. ---- Contributor(s): H. S. P. Müller; 06, 2006; 12, 2021 ----
