The experiments were performed \non beamline BL23SU at SPring-8, Japan. The hydrated dR films were prepared by exposing the cooled dR film surface to water vapor. The XANES spectra were then obtained by measuring the sample drain current. The soft X-ray irradiation treatment led to an increase in the intensity of the s*(C=O) peak (around 532 eV) and a decrease in the intensity of the s*(C–O) peak around 538 eV). Furthermore, a characteristic peak was observed at around 534–536 eV in the hydrated dR film after irradiation. This peak, which was ascribed to a newly formed carboxyl group, was not observed in the XANES \nspectrum of the dry dR film after irradiation. This carboxyl group was considered to originate from the reaction of a nearby water molecule with the carbonyl group produced by the direct ionization of dR. This structure may\nbe formed at the strand-break termini of DNA after radiation damage. Therefore, waters of hydration may play a protective role against irreparable \nstrand breakage.","subitem_description_type":"Abstract"}]},"item_8_publisher_8":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"American Institute of Physics"}]},"item_8_relation_14":{"attribute_name":"DOI","attribute_value_mlt":[{"subitem_relation_type_id":{"subitem_relation_type_id_text":"10.1063/1.5084606","subitem_relation_type_select":"DOI"}}]},"item_8_relation_17":{"attribute_name":"関連サイト","attribute_value_mlt":[{"subitem_relation_name":[{"subitem_relation_name_text":"https://aip.scitation.org/doi/pdf/10.1063/1.5084606"}],"subitem_relation_type_id":{"subitem_relation_type_id_text":"https://aip.scitation.org/doi/pdf/10.1063/1.5084606","subitem_relation_type_select":"URI"}}]},"item_access_right":{"attribute_name":"アクセス権","attribute_value_mlt":[{"subitem_access_right":"metadata only access","subitem_access_right_uri":"http://purl.org/coar/access_right/c_14cb"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"藤井, 健太郎"}],"nameIdentifiers":[{"nameIdentifier":"501070","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"横谷, 明徳"}],"nameIdentifiers":[{"nameIdentifier":"501071","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"藤井 健太郎","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"501072","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"横谷 明徳","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"501073","nameIdentifierScheme":"WEKO"}]}]},"item_language":{"attribute_name":"言語","attribute_value_mlt":[{"subitem_language":"eng"}]},"item_resource_type":{"attribute_name":"資源タイプ","attribute_value_mlt":[{"resourcetype":"journal article","resourceuri":"http://purl.org/coar/resource_type/c_6501"}]},"item_title":"XANES spectral changes of hydrated deoxyribose induced by  K-shell ionization of oxygen","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"XANES spectral changes of hydrated deoxyribose induced by  K-shell ionization of oxygen"}]},"item_type_id":"8","owner":"1","path":["1"],"pubdate":{"attribute_name":"公開日","attribute_value":"2019-02-12"},"publish_date":"2019-02-12","publish_status":"0","recid":"49599","relation_version_is_last":true,"title":["XANES spectral changes of hydrated deoxyribose induced by  K-shell ionization of oxygen"],"weko_creator_id":"1","weko_shared_id":-1},"updated":"2023-05-15T23:19:02.969666+00:00"}
