The Missing Link of Sulfur Chemistry in TMC-1: The Detection of //c//-C₃H₂S from the GOTHAM Survey
Astrophys. J. 982, Art. No. 191 (2025).
The molecule was identified through line-stacking in the course of the GOTHAM survey of TMC-1 carried out with the 100 m GBT dish and covering a large fraction of the 3.9 to 36.4 GHz region. An excitation temperature of ~5 K was derived. The abundance ratio of CH₂CCS/c-C₃H₂S is about 10 while that of HCCCHS/c-C₃H₂S is about 2.5 (taking into account the differences in assumed source diameters).
