We calculated all CEBEs of the model molecules using the ΔE_ks approach. Our simulated Cls photoelectron and C Kα emission spectra are in good agreement with our measurements.), (2)Electronic structure of a Mn_12 molecular magnet: Theory and experiment, (3)Simulation of resonant X-ray emission spectra of ethylene and benzene molecules (We proposed a theoretical method for analysis of resonant X-ray emission spectra from ab initio MO calculation using single configuration approximation as an intermediate state.) (4)Theoretical analysis of Auger electron spectra of 2nd periodic element containing substances(Simulated AES and valence XES of four substances [graphite, GaN, SiO_2, LiF] by DFT calculations using model molecules are in considerably good accordance with the experimental ones. Experimental AES of the substances were classified in each range of 1s-2s2s, 1s-2s2p and 1s-2p2p transitions for C, N, 0 and F KVV' spectra, respectively.), (5)XPS Spectral Simulation of Chitosan in Thermal Decomposition Process (6)X-Ray Photoelectron Spectral Analysis for Carbon Allotropes (We performed DFT calculations using Amsterdam density functional (ADF) program to simulate X-ray photoelectron spectra for carbon allotropes (diamond, graphite, single-wall carbon nanotube(SWCN), and fullerene C_60). We firstly described the simulation method for valence electron spectra to distinguish the diamond phase of carbon from the graphite carbon, and secondly evaluated the WD values from the differences between the calculated core-electron binding energies(CEBE)s of the model molecules (using ΔE_ks approach(like ΔSCF method in MO))and experimental CEBEs of carbon allotropes. The WD values of carbon allotropes correspond to the order of experimental values (CNT < graphite < diamond < C_<60>) for work functions obtained from accurate cylindrical analyzer(CMA)detector by Goto's and co-workers.)\nIn (B), three investigations were performed as follows; (1) Simulations of thermal decomposition for carbon allotrope molecules by a quantum molecular dynamics method (In order to simulate thermal decomposition of carbon allotrope molecules [single walled carbon nanotube(SWNT)models{arm-chair(C_<54>H_<12>), zigzag(C_<50>H_<10>) types), C_<60>, and graphic model C_<42>H_<16>], we used MD with semi-empirical AM1 MO method(a kind of QMD).) (2)Simulation of SIMS for monomer and dimer of lignin under the assumption of thermal decomposition using QMD method(The thermal decomposition of the monomer and dimer of lignin has been simulated by quantum molecular dynamics(DMD) method. We obtained the thermally decomposed fragments with positive, neural and negative changes from SCF MO calculation at each data of the last MD step, and simulated the fragment distribution of the monomer and dimer lignins from the last step in 30〜40 runs. Simulated mass numbers of positively and negatively charged fragments for lignin monomer and dimer showed considerably good accordance with the experimental results in TOF-SIMS observed by Saito and co-workers.), (3)Fragments Distribution of Thermal Decomposition for PS and PET with QMD Calculations by Considering the Excited and Charged Model Molecules(Simulations by a quantum molecular dynamics(QMD) (MD with MO) method were demonstrated on the thermal decomposition of PS and PET polymers using the model molecules at the ground state including excited and positive charged states. The calculated neutral, positive and negative fragment distributions of PS and PET models with 0.82 eV energy control were obtained as (93.5, 2.3, and 4.3%), and(87.8, 5.3, and 6.9%) to the total fragments, respectively. The ratios seem to correspond well to the values observed experimentally in SIMS.).","subitem_description_type":"Abstract"}]},"item_9_description_22":{"attribute_name":"内容記述","attribute_value_mlt":[{"subitem_description":"研究課題/領域番号:18550013, 研究期間(年度):2006 – 2007","subitem_description_type":"Other"},{"subitem_description":"出典：研究課題「理論的表面分光装置の開発」課題番号18550013\n（KAKEN：科学研究費助成事業データベース（国立情報学研究所）） \n（https://kaken.nii.ac.jp/ja/report/KAKENHI-PROJECT-18550013/185500132007kenkyu_seika_hokoku_gaiyo/）を加工して作成","subitem_description_type":"Other"}]},"item_9_description_5":{"attribute_name":"提供者所属","attribute_value_mlt":[{"subitem_description":"金沢大学大学院自然科学研究科","subitem_description_type":"Other"}]},"item_9_identifier_registration":{"attribute_name":"ID登録","attribute_value_mlt":[{"subitem_identifier_reg_text":"10.24517/00059827","subitem_identifier_reg_type":"JaLC"}]},"item_9_relation_28":{"attribute_name":"関連URI","attribute_value_mlt":[{"subitem_relation_name":[{"subitem_relation_name_text":"https://kaken.nii.ac.jp/ja/search/?kw=20293334"}],"subitem_relation_type_id":{"subitem_relation_type_id_text":"https://kaken.nii.ac.jp/ja/search/?kw=20293334","subitem_relation_type_select":"URI"}},{"subitem_relation_name":[{"subitem_relation_name_text":"https://kaken.nii.ac.jp/ja/grant/KAKENHI-PROJECT-18550013/"}],"subitem_relation_type_id":{"subitem_relation_type_id_text":"https://kaken.nii.ac.jp/ja/grant/KAKENHI-PROJECT-18550013/","subitem_relation_type_select":"URI"}},{"subitem_relation_name":[{"subitem_relation_name_text":"https://kaken.nii.ac.jp/ja/report/KAKENHI-PROJECT-18550013/185500132007kenkyu_seika_hokoku_gaiyo/"}],"subitem_relation_type_id":{"subitem_relation_type_id_text":"https://kaken.nii.ac.jp/ja/report/KAKENHI-PROJECT-18550013/185500132007kenkyu_seika_hokoku_gaiyo/","subitem_relation_type_select":"URI"}}]},"item_9_version_type_25":{"attribute_name":"著者版フラグ","attribute_value_mlt":[{"subitem_version_resource":"http://purl.org/coar/version/c_ab4af688f83e57aa","subitem_version_type":"AM"}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2022-05-16"}],"displaytype":"detail","filename":"SC-PR-ENDO-K-kaken 2010-4p.pdf","filesize":[{"value":"168.4 kB"}],"format":"application/pdf","licensetype":"license_11","mimetype":"application/pdf","url":{"label":"SC-PR-ENDO-K-kaken 2010-4p.pdf","url":"https://kanazawa-u.repo.nii.ac.jp/record/53545/files/SC-PR-ENDO-K-kaken 2010-4p.pdf"},"version_id":"2c39f8ec-a1e3-4c4e-ab44-ab072ae382e0"}]},"item_language":{"attribute_name":"言語","attribute_value_mlt":[{"subitem_language":"jpn"}]},"item_resource_type":{"attribute_name":"資源タイプ","attribute_value_mlt":[{"resourcetype":"research report","resourceuri":"http://purl.org/coar/resource_type/c_18ws"}]},"item_title":"理論的表面分光装置の開発","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"理論的表面分光装置の開発"},{"subitem_title":"Development of theoretical surface spectral apparatus","subitem_title_language":"en"}]},"item_type_id":"9","owner":"18","path":["2826"],"pubdate":{"attribute_name":"公開日","attribute_value":"2022-05-16"},"publish_date":"2022-05-16","publish_status":"0","recid":"53545","relation_version_is_last":true,"title":["理論的表面分光装置の開発"],"weko_creator_id":"18","weko_shared_id":-1},"updated":"2023-07-27T13:06:36.219138+00:00"}
