Non-detection Of HC(S)SH: Estimating Upper Limits And Constraining Chemistry
The search for dithioformic acid (t-HC(S)SH) in star-forming regions is crucial for understanding interstellar sulfur chemistry and addressing the ‘missing sulfur’ problem. Motivated by a recent claim of t-HC(S)SH detection […]
