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. The first two lines display somewhat and barely resolved ¹⁴N hyperfine structure splitting, respectively. The next two lines are somewhat broadened, and the last line is blended. Members with n = 2 and n ≥ 4 were not detected. The abundance ratios of NCS/NC₃S is about 5.6.
