| The molecules was identified in the course of a molecular line survey between 31.0 and 50.3 GHz through four unblendand two slightly blended transitions. One further line was heavily blended and the one at highest frequency was slightly too weak to be observed. | The molecule was identified in the course of a molecular line survey with the 40 m Yebes radio telescope between 31.0 and 50.3 GHz through seven transitions of which one was slightly and one heavily blended. The rotational temperature is about 13.5 K. It is less abundant than sodium (iso) cyanide by a factor of about 250 to 750.\\ |
| The identification relied on quantum chemical calculations in the absense of laboratory spectroscopic data. The rotational temperature is roughly 17 K. The abundance ratios of HMgC<sub>3</sub>N : MgCN : MgC<sub>3</sub>N : MgC<sub>5</sub>N : MgNC : HMgNC are about 30 : 7.4 : 93 : 47 : 130 : 6.\\ | |
