While numerous works have been carried out in the past to characterise SOA at a molecular level, the structural elucidation of SOA compounds remains challenging owing to the lack of authentic standard compounds. In this work, the structures of alpha-pinene originating dimeric esters in SOA with m/z  [Formula: see text] and m/z  [Formula: see text] were characterised using UPLC/ESI(-)IMS-TOFMS² (ultra-performance liquid chromatography coupled to ion mobility spectrometry tandem time-of-flight mass spectrometry). The measured collision cross-section  [Formula: see text] values were compared to theoretically calculated [Formula: see text] values. Selected product ions of dimeric compounds and the authentic standard compounds of product ions were subjected to CO₂-IMS-TOFMS for more detailed structural characterisation. Our results were consistent with previously reported subunits of the m/z 357 (terpenylic acid and cis-pinic acid), and the m/z 367 (10-hydroxy-cis-pinonic acid and cis-pinic acid) ions. The measured and calculated  [Formula: see text] values of m/z 367 ions further support the conclusion of earlier structural characterisation; however, the structure of the m/z 357 ion remains vague and requires further characterisation studies with a synthesised reference compound.","subitem_description_type":"Other"}]},"item_10001_publisher_8":{"attribute_name":"Publisher","attribute_value_mlt":[{"subitem_publisher":"MDPI "}]},"item_10001_relation_14":{"attribute_name":"DOI","attribute_value_mlt":[{"subitem_relation_type":"isIdenticalTo","subitem_relation_type_id":{"subitem_relation_type_id_text":"info:doi/10.3390/atmos12010017","subitem_relation_type_select":"DOI"}}]},"item_10001_relation_17":{"attribute_name":"Related site","attribute_value_mlt":[{"subitem_relation_type_id":{"subitem_relation_type_id_text":"https://www.mdpi.com/2073-4433/12/1/17","subitem_relation_type_select":"URI"}}]},"item_10001_rights_15":{"attribute_name":"Rights","attribute_value_mlt":[{"subitem_rights":"© 2020 The Author(s)."}]},"item_10001_source_id_9":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"2073-4433","subitem_source_identifier_type":"ISSN"}]},"item_10001_version_type_20":{"attribute_name":"Author's flag","attribute_value_mlt":[{"subitem_version_resource":"http://purl.org/coar/version/c_970fb48d4fbd8a85","subitem_version_type":"VoR"}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2021-02-24"}],"displaytype":"detail","filename":"Iinuma-2021-Structural Characterisation of Dim.pdf","filesize":[{"value":"6.9 MB"}],"format":"application/pdf","license_note":"Creative Commons Attribution 4.0 International(https://creativecommons.org/licenses/by/4.0/)","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"Iinuma-2021-Structural Characterisation of Dim","url":"https://oist.repo.nii.ac.jp/record/1942/files/Iinuma-2021-Structural Characterisation of Dim.pdf"},"version_id":"15406de3-f3eb-4d57-9bbf-e6d9af75dee4"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"SOA","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"ion mobility","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"collision cross-section","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"α-pinene SOA dimers","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"stereochemical assignment","subitem_subject_language":"en","subitem_subject_scheme":"Other"}]},"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":"Structural Characterisation of Dimeric Esters in α-Pinene Secondary Organic Aerosol Using N2 and CO2 Ion Mobility Mass Spectrometry","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Structural Characterisation of Dimeric Esters in α-Pinene Secondary Organic Aerosol Using N2 and CO2 Ion Mobility Mass Spectrometry","subitem_title_language":"en"}]},"item_type_id":"10001","owner":"30","path":["167"],"pubdate":{"attribute_name":"公開日","attribute_value":"2021-02-24"},"publish_date":"2021-02-24","publish_status":"0","recid":"1942","relation_version_is_last":true,"title":["Structural Characterisation of Dimeric Esters in α-Pinene Secondary Organic Aerosol Using N2 and CO2 Ion Mobility Mass Spectrometry"],"weko_creator_id":"30","weko_shared_id":30},"updated":"2023-06-26T11:39:55.668184+00:00"}
