TMC-1, the starless core sulfur factory: Discovery of NCS, HCCS, H<sub>2</sub>CCS, H<sub>2</sub>CCCS, and C<sub>4</sub>S and detection of C<sub>5</sub>S
Astron. Astrophys. 648, Art. No. L3 (2021).
The ethenthionyl radical HCCS was identified through 2 1H hyperfine components of the 2Π3/2 J = 7/2 − 5/2 transition near 41.1 GHz 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. The column density is slightly lower than that of H2CCS and about a factor of ten lower than that of HCS.
