The spectrum reveals several new features not previously reported in the literature. Vibronic structure has been observed, notably in the low energy absorption dipole forbidden band assigned to the (4π←3π) (1Δ←1Σ+) transition, with a new weak transition assigned to (1Σ-←1Σ+) reported here for the first time. The absolute optical oscillator strengths are determined for ground state to 1Σ+ and 1Π transitions. Based on our recent measurements of differential cross sections for the optically allowed (1Σ+ and 1Π) transitions of COS by electron impact, the optical oscillator strength f0 value and integral cross sections (ICSs) are derived by applying a generalized oscillator strength analysis. Subsequently, ICSs predicted by the scaling are confirmed down to 60 eV in the intermediate energy region. The measured absolute photoabsorption cross sections have been used to calculate the photolysis lifetime of carbonyl sulphide in the upper stratosphere (20-50 km).CeFITec – Centro de Física e Investigação TecnológicaDF – Departamento de FísicaRUNLimão-Vieira, P.Ferreira Da Silva, F.Almeida, DiogoHoshino, MasamitsuTanaka, HideakiMogi, DaisukeTanioka, T.Mason, Nigel J.Hoffmann, Soren VronningHubin-Franskin, Marie JeanneDelwiche, Jacques P.2018-05-08T22:11:32Z2015-02-142015-02-14T00:00:00Zinfo:eu-repo/semantics/publishedVersioninfo:eu-repo/semantics/articleapplication/pdfhttps://doi.org/10.1063/1.4907200eng0021-9606PURE: 2896922http://www.scopus.com/inward/record.url?scp=84923804744&partnerID=8YFLogxKhttps://doi.org/10.1063/1.4907200info:eu-repo/semantics/openAccessreponame:Repositório Científico de Acesso Aberto de Portugal (Repositórios Cientìficos)instname:Agência para a Sociedade do Conhecimento (UMIC) - FCT - Sociedade da Informaçãoinstacron:RCAAP2024-03-11T04:19:37Zoai:run.unl.pt:10362/36243Portal AgregadorONGhttps://www.rcaap.pt/oai/openaireopendoar:71602024-03-20T03:30:25.010720Repositório Científico de Acesso Aberto de Portugal (Repositórios Cientìficos) - Agência para a Sociedade do Conhecimento (UMIC) - FCT - Sociedade da Informaçãofalse
