Five rotational transitions, //J"// = 7 to 9 and 11 and 12 were observable in theory between 87 and 143 GHz in the course of a molecular line survey carried out with the IRAM 30 m radiotelecope on Pico Veleta, Spain. //J"// = 7 and 9 were seen with reasonable signal-to-noise ratio. //J"// = 8 was fully overlapped, and //J"// = 11 and 12 were overlapped in part, but could be included in the analysis. The rotational temperature of around 21 K is similar to that of MgNC and maybe slightly warmer than that of MgCN. Its column density is slightly smaller than that of MgCN, and much smaller, by a factor of about 20, than that of MgNC. | Five rotational transitions, //J"// = 7 to 9 and 11 and 12 were observable in theory between 87 and 143 GHz in the course of a molecular line survey carried out with the IRAM 30 m radiotelecope on Pico Veleta, Spain. //J"// = 7 and 9 were seen with reasonable signal-to-noise ratio. //J"// = 8 was fully overlapped, and //J"// = 11 and 12 were overlapped in part, but could be included in the analysis.
