The temperature dependences of the translational diffusion coefficients (D’s) of both the radicals and the parent molecules can be expressed by the Arrhenius relationship. The activation energies (ED) for diffusion of the radicals are larger than those of the parent molecules and the difference in ED depends on the molecular size. The different ED is explained in terms of the molecular volume dependence of ED; that is, larger molecular volumes of the radicals could be the cause of the larger ED. The larger apparent molecular volumes of the radicals are consistent with a model of microscopic aggregation of the surrounding molecules around the radical.</jats:p>"}]}],"creator":[{"@id":"https://cir.nii.ac.jp/crid/1410001205667275136","@type":"Researcher","personIdentifier":[{"@type":"NRID","@value":"9000107336446"},{"@type":"NRID","@value":"9000258154144"},{"@type":"NRID","@value":"9000401696172"},{"@type":"NRID","@value":"9000004782273"},{"@type":"NRID","@value":"9000006849793"},{"@type":"NRID","@value":"9000258318122"},{"@type":"RESEARCHMAP","@value":"https://researchmap.jp/read0142740"}],"foaf:name":[{"@value":"Koichi Okamoto"}],"jpcoar:affiliationName":[{"@value":"Department of Chemistry, Faculty of Science, Kyoto University, Kyoto, 606 Japan"}]},{"@id":"https://cir.nii.ac.jp/crid/1381981471371434880","@type":"Researcher","foaf:name":[{"@value":"Masahide Terazima"}],"jpcoar:affiliationName":[{"@value":"Department of Chemistry, Faculty of Science, Kyoto University, Kyoto, 606 Japan"}]},{"@id":"https://cir.nii.ac.jp/crid/1381981471371434881","@type":"Researcher","foaf:name":[{"@value":"Noboru Hirota"}],"jpcoar:affiliationName":[{"@value":"Department of Chemistry, Faculty of Science, Kyoto University, Kyoto, 606 Japan"}]}],"publication":{"publicationIdentifier":[{"@type":"PISSN","@value":"00219606"},{"@type":"EISSN","@value":"10897690"}],"prism:publicationName":[{"@value":"The Journal of Chemical Physics"}],"dc:publisher":[{"@value":"AIP Publishing"}],"prism:publicationDate":"1995-12-22","prism:volume":"103","prism:number":"24","prism:startingPage":"10445","prism:endingPage":"10452"},"reviewed":"false","url":[{"@id":"https://pubs.aip.org/aip/jcp/article-pdf/103/24/10445/19290197/10445_1_online.pdf"}],"createdAt":"2002-07-26","modifiedAt":"2024-02-07","relatedProduct":[{"@id":"https://cir.nii.ac.jp/crid/1360846644035131904","@type":"Article","relationType":["isReferencedBy"],"jpcoar:relatedTitle":[{"@value":"Time-Resolved Thermodynamic Properties of Intermediate Species during Photochemical Reactions"}]},{"@id":"https://cir.nii.ac.jp/crid/1361975842063993216","@type":"Article","resourceType":"学術雑誌論文(journal article)","relationType":["isReferencedBy"],"jpcoar:relatedTitle":[{"@value":"The role of molecular and radical mobility in the creation of CO2 molecules and OH groups in PADC irradiated with C and O ions"}]},{"@id":"https://cir.nii.ac.jp/crid/1520572358001443200","@type":"Article","relationType":["isCitedBy"],"jpcoar:relatedTitle":[{"@value":"光化学反応中間体ラジカルの拡散過程"},{"@language":"ja-Kana","@value":"コウカガク ハンノウ チュウカンタイ ラジカル ノ カクサン カテイ"}]},{"@id":"https://cir.nii.ac.jp/crid/1522825129753516544","@type":"Article","relationType":["isCitedBy"],"jpcoar:relatedTitle":[{"@value":"Time-Resolved Thermodynamic Properties of Intermediate Species during Photochemical Reactions"},{"@language":"ja-Kana","@value":"Time Resolved Thermodynamic Properties of Intermediate Species during Photochemical Reactions"}]},{"@id":"https://cir.nii.ac.jp/crid/2051151842062066944","@type":"Article","relationType":["isReferencedBy"],"jpcoar:relatedTitle":[{"@value":"Study on the translational diffusion of transient species in 1-alkyl-3-methylimidazolium-based ionic liquids by transient grating spectroscopy"}]}],"dataSourceIdentifier":[{"@type":"CROSSREF","@value":"10.1063/1.469894"},{"@type":"CIA","@value":"80008729190"},{"@type":"OPENAIRE","@value":"doi_dedup___::0efa41330757b3cd94d6c7a37cf2a45d"},{"@type":"CROSSREF","@value":"10.1246/bcsj.77.23_references_DOI_MTWdaSW9VZGf8B9lfxk1EpWrkTO"},{"@type":"CROSSREF","@value":"10.1016/j.polymdegradstab.2019.04.007_references_DOI_MTWdaSW9VZGf8B9lfxk1EpWrkTO"},{"@type":"CROSSREF","@value":"10.1246/bcsj.20220099_references_DOI_MTWdaSW9VZGf8B9lfxk1EpWrkTO"}]}
