| | The 2<sub>02</sub> − 1<sub>01</sub> transition near 37.49 GHz with fine and hyperfine structure splitting was detected toward TMC-1 using the Yebes 40 m radio telescope in the course of a molecular line survey. The derived H<sub>2</sub>CCN to HDCCN ratio is 20 ± 4, i.e., ~40 per H atom, quite normal for TMC-1. |
