These processes start in light-harvesting complexes, which contain special photosynthetic pigments. The exploration of unique mechanisms in light-harvesting complexes is directly related to studies, such as artificial photosynthesis or biosignatures in astrobiology. We examined, through ab initio calculations, the light absorption and EET processes using cluster models of light-harvesting complexes in purple bacteria (LH2). We evaluated absorption spectra and energy transfer rates using the LH2 monomer and dimer models to reproduce experimental results. After the calibration tests, a LH2 aggregation model, composed of 7 or 19 LH2s aligned in triangle lattice, was examined. We found that the light absorption is red shifted and the energy transfer becomes faster as the system size increases. We also found that EET is accelerated by exchanging the central pigments to lower energy excited pigments. As an astrobiological application, we calculated light absorptions efficiencies of the LH2 in different photoenvironments.","subitem_description_type":"Abstract"}]},"item_5_publisher_27":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"Taylor & Francis"}]},"item_5_relation_11":{"attribute_name":"DOI","attribute_value_mlt":[{"subitem_relation_type_id":{"subitem_relation_type_id_text":"10.1080/00268976.2014.998305","subitem_relation_type_select":"DOI"}}]},"item_5_select_15":{"attribute_name":"著者版フラグ","attribute_value_mlt":[{"subitem_select_item":"author"}]},"item_5_source_id_7":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"0026-8976","subitem_source_identifier_type":"ISSN"}]},"item_5_source_id_9":{"attribute_name":"書誌レコードID","attribute_value_mlt":[{"subitem_source_identifier":"AA00745902","subitem_source_identifier_type":"NCID"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"Komatsu, Yu"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Kayanuma, Megumi"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Shoji, Mitsuo"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Yabana, Kazuhiro"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Shiraishi, Kenji"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Umemura, Masayuki"}],"nameIdentifiers":[{}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2016-07-01"}],"displaytype":"detail","filename":"MP_113-12.pdf","filesize":[{"value":"997.0 kB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"MP_113-12","url":"https://tsukuba.repo.nii.ac.jp/record/34576/files/MP_113-12.pdf"},"version_id":"bc8fce41-1956-4eb5-bb5e-e0f4deaaeaeb"}]},"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":"Light absorption and excitation energy transfer calculations in primitive photosynthetic bacteria","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Light absorption and excitation energy transfer calculations in primitive photosynthetic bacteria"}]},"item_type_id":"5","owner":"1","path":["1203","3125","3124","2843","3126"],"pubdate":{"attribute_name":"公開日","attribute_value":"2015-07-30"},"publish_date":"2015-07-30","publish_status":"0","recid":"34576","relation_version_is_last":true,"title":["Light absorption and excitation energy transfer calculations in primitive photosynthetic bacteria"],"weko_creator_id":"1","weko_shared_id":5},"updated":"2022-04-27T09:03:26.994271+00:00"}
