| | The isotopolog was identified in the Protostellar Interferometric Line Survey (PILS) toward the solar-like protostar IRAS 16293−2422 B. Eight lines were detected that were deemed to be unblended or only slightly blended. Several other transitions were covered, but most of them were severely blended. The derived CH<sub>2</sub>DSH to CH<sub>3</sub>SH ratio is about 0.055. An earlier search for CH<sub>3</sub>SD by [[https://doi.org/10.1051/0004-6361/201834472|O. Zhakharenko et al.]], //Astron. Astrophys.// **621**, Art. No. A114 (2019) was unsuccessful and, with respect to the present finding, not particularly constraining.\\ |
