| The ethenthione, H<sub>2</sub>C<sub>2</sub>S, and propadienthione, H<sub>2</sub>C<sub>3</sub>S, molecules were identified through 6 and 7 //a//-type transitions, respectively, with //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 32.8 and 49.2 GHz. The column density of H<sub>2</sub>C<sub>2</sub>S is about a factor of 100 lower than that of H<sub>2</sub>CS and about a factor of two higher than that of H<sub>2</sub>C<sub>3</sub>S.\\ | The propargyl radical was identified through the six strongest hyperfine components of the 2<sub>02</sub> − 1<sub>01</sub> rotational transition around 37460 MHz 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 32.8 and 49.2 GHz. The column density of CH<sub>2</sub>CCH is only slightly smaller than that of CH<sub>3</sub>CCH, a closed shell species.\\ |
