| | //Astron. Astrophys.// **650**, Art. No. L15 (2021).\\ |
| | The molecule was identified through 15 //a//-type transitions with 7 ≤ //J// ≤ 12 and //K<sub>a</sub>// = 0 and 1 in the course of a molecular line survey of the prototypical cold dark molecular cloud TMC-1 carried out with the Yebes 40 m radio telescope between 31.0 and 50.4 GHz. A value of //T//<sub>rot</sub> = 8.0 ± 0.5 K was derived. The column density of monodeuterated methylcyanoacetylene is about a factor of 22 lower than that of the fully hydrogenated isotopolog; thus the H/D ratio per H atom is about 66.\\ |
