HOSO is found to be a nonplanar radical in its ground electronic state with a torsion angle calculated to be 49.7\u00b0. The lowest three doublet electronic states are characterized by a large transition dipole moment and are implicated in the photodissociation of HOSO in the gas phase to generate SO and OH as products. Sulfur dioxide and hydrogen products may also result after UV absorption to reach the first excited state, and this channel competes with the production of OH and SO.<\/jats:p>","DOI":"10.1063\/1.5119704","type":"journal-article","created":{"date-parts":[[2019,9,18]],"date-time":"2019-09-18T13:36:22Z","timestamp":1568813782000},"update-policy":"https:\/\/doi.org\/10.1063\/aip-crossmark-policy-page","source":"Crossref","is-referenced-by-count":16,"title":["Photochemistry of HOSO radical in the gas phase"],"prefix":"10.1063","volume":"151","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-6258-7191","authenticated-orcid":false,"given":"Tarek","family":"Trabelsi","sequence":"first","affiliation":[{"name":"Department of Earth and Environment Science, University of Pennsylvania 1 , Philadelphia, Pennsylvania 19104-6243, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-4526-3624","authenticated-orcid":false,"given":"Josep M.","family":"Anglada","sequence":"additional","affiliation":[{"name":"Departament de Qu\u00edmica Biol\u00f2gica (IQAC \u2013 CSIC) 2 , c\/Jordi Girona 18, E-08034 Barcelona, Spain"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-2784-6319","authenticated-orcid":false,"given":"Manuel F.","family":"Ruiz-L\u00f3pez","sequence":"additional","affiliation":[{"name":"Laboratoire de Physique et Chimie Th\u00e9oriques, UMR CNRS 7019, University of Lorraine, CNRS 3 , BP 70239, 54506 Vandoeuvre-l\u00e8s-Nancy, France"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-5461-1486","authenticated-orcid":false,"given":"Joseph S.","family":"Francisco","sequence":"additional","affiliation":[{"name":"Department of Earth and Environment Science, University of Pennsylvania 1 , Philadelphia, Pennsylvania 19104-6243, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"317","published-online":{"date-parts":[[2019,9,18]]},"reference":[{"issue":"24","key":"2023062601454813600_c1","doi-asserted-by":"publisher","first-page":"9967","DOI":"10.1021\/ja211632r","volume":"134","year":"2012","journal-title":"J.
