Exploiting thioformaldehyde (H\n                    <jats:sub>2<\/jats:sub>\n                    CS) and its thiohydroxycarbene isomer (HCSH), we deliver compelling testimony via laboratory experiments, electronic-structure theory, astrochemical modeling, and quasi-classical trajectory studies that these organosulfur species can be efficiently formed in star-forming regions such as Sagittarius B2 through bimolecular reactions involving hydrogen sulfide and methylidyne radicals. These elementary mechanisms are of fundamental importance to aid our understanding of how carbon and sulfur chemistries are connected in deep space, thus expanding our view on the sulfur cycle in the Galaxy.\n                  <\/jats:p>","DOI":"10.1073\/pnas.2004881117","type":"journal-article","created":{"date-parts":[[2020,8,28]],"date-time":"2020-08-28T19:49:29Z","timestamp":1598644169000},"page":"22712-22719","update-policy":"https:\/\/doi.org\/10.1073\/pnas.cm10313","source":"Crossref","is-referenced-by-count":23,"title":["A chemical dynamics study on the gas phase formation of thioformaldehyde (H\n                    <sub>2<\/sub>\n                    CS) and its thiohydroxycarbene isomer (HCSH)"],"prefix":"10.1073","volume":"117","author":[{"given":"Srinivas","family":"Doddipatla","sequence":"first","affiliation":[{"name":"Department of Chemistry, University of Hawai\u2019i at M\u0101noa, Honolulu, HI 96822;"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Chao","family":"He","sequence":"additional","affiliation":[{"name":"Department of Chemistry, University of Hawai\u2019i at M\u0101noa, Honolulu, HI 96822;"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-7256-672X","authenticated-orcid":false,"given":"Ralf I.","family":"Kaiser","sequence":"additional","affiliation":[{"name":"Department of Chemistry, University of Hawai\u2019i at M\u0101noa, Honolulu, HI 96822;"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-3124-1179","authenticated-orcid":false,"given":"Yuheng","family":"Luo","sequence":"additional","affiliation":[{"name":"Department of Chemistry, University of Hawai\u2019i at M\u0101noa, Honolulu, HI 96822;"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-0638-1353","authenticated-orcid":false,"given":"Rui","family":"Sun","sequence":"additional","affiliation":[{"name":"Department of Chemistry, University of Hawai\u2019i at M\u0101noa, Honolulu, HI 96822;"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Galiya R.","family":"Galimova","sequence":"additional","affiliation":[{"name":"Department of Chemistry and Biochemistry, Florida International University, Miami, FL 33199;"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-7233-3133","authenticated-orcid":false,"given":"Alexander M.","family":"Mebel","sequence":"additional","affiliation":[{"name":"Department of Chemistry and Biochemistry, Florida International University, Miami, FL 33199;"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-5178-3656","authenticated-orcid":false,"given":"Tom J.","family":"Millar","sequence":"additional","affiliation":[{"name":"School of Mathematics and Physics, Queen\u2019s University Belfast, Belfast BT7 1NN, Northern Ireland, United Kingdom"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"341","published-online":{"date-parts":[[2020,8,28]]},"reference":[{"key":"e_1_3_4_1_2","doi-asserted-by":"publisher","DOI":"10.1086\/180784"},{"key":"e_1_3_4_2_2","doi-asserted-by":"publisher","DOI":"10.1051\/0004-6361\/201527268"},{"key":"e_1_3_4_3_2","doi-asserted-by":"publisher","DOI":"10.1051\/0004-6361\/201935200"},{"key":"e_1_3_4_4_2","doi-asserted-by":"publisher","DOI":"10.1051\/0004-6361:20030712"},{"key":"e_1_3_4_5_2","doi-asserted-by":"publisher","DOI":"10.1051\/0004-6361\/201629862"},{"key":"e_1_3_4_6_2","doi-asserted-by":"publisher","DOI":"10.1051\/0004-6361:20077229"},{"key":"e_1_3_4_7_2","first-page":"466","article-title":"Organo-sulphur chemistry in dense interstellar clouds","volume":"231","author":"Millar T.
