For both samples, the integrated solid effect (ISE) is used to polarize the13C spin system in magnetic fields of 350-400 mT. In the benzoic acid sample, the13C spin polarization is enhanced up to 0.12% through directelectron-to-13C polarization transfer without performing dynamic1H polarization followed by 1H-13C cross polarization. In5addition, ISE has been successfully applied for the first time to polarize naturally abundant 13C spins in a microdiamond sample to 0.01%. To characterize the buildup of the13C polarization, we discuss the efficiencies of direct polarization transfer be-tween the electron and13C spins as well as that of13C–13C spin diffusion, examining various parameters which are beneficial or detrimental for successful bulk dynamic13C polarization.","subitem_description_type":"Abstract"}]},"item_8_publisher_8":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"Copernicus Publications"}]},"item_8_relation_14":{"attribute_name":"DOI","attribute_value_mlt":[{"subitem_relation_type_id":{"subitem_relation_type_id_text":"10.5194/mr-2-33-2021","subitem_relation_type_select":"DOI"}}]},"item_8_relation_17":{"attribute_name":"関連サイト","attribute_value_mlt":[{"subitem_relation_type_id":{"subitem_relation_type_id_text":"https://mr.copernicus.org/articles/2/33/2021/mr-2-33-2021.html","subitem_relation_type_select":"URI"}}]},"item_8_source_id_9":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"0730-725X","subitem_source_identifier_type":"ISSN"}]},"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":"Miyanishi, Koichiro"}],"nameIdentifiers":[{"nameIdentifier":"1008131","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"F.
