The authors are extremely grateful to Professor Eugen Illenberger from the Free University Berlin, Germany, for fruitful and lively discussions.Electron transfer in alkali-molecule collisions to gas phase thymine and uracil yielding H- formation is selectively controlled in the energy range between 5.3 and 66.1 eV. By tuning the collision energy, electron transfer from the alkali to partly deuterated thymine, methylated thymine at the N-1 and methylated uracil at the N-3 positions, H- loss proceeds not only through the breaking of the (C-H) against (N-H) bonds but also through N-1 against N-3 sites. Such selectivity, as far as bond and site are concerned, is here reported for the first time by electron transfer induced dissociation experiments in alkali-molecule collisions.CeFITec – Centro de Física e Investigação TecnológicaDF – Departamento de FísicaRUNAlmeida, Diogoda Silva, Filipe FerreiraGarcia, GustavoLimao-Vieira, Paulo2018-02-08T23:01:25Z2013-01-082013-01-08T00:00:00Zinfo:eu-repo/semantics/publishedVersioninfo:eu-repo/semantics/articleapplication/pdfhttp://hdl.handle.net/10362/30083eng0031-9007PURE: 449865https://doi.org/10.1103/PhysRevLett.110.023201info: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:RCAAP2024-03-11T04:16:34Zoai:run.unl.pt:10362/30083Portal AgregadorONGhttps://www.rcaap.pt/oai/openaireopendoar:71602024-03-20T03:29:24.134855Repositório Científico de Acesso Aberto de Portugal (Repositórios Cientìficos) - Agência para a Sociedade do Conhecimento (UMIC) - FCT - Sociedade da Informaçãofalse
