In this study, the Raman spectra of the C–H symmetric\nstretch region of CH4 enclathrated within various sH hydrates and structure I CH4 hydrates were\nanalyzed in the temperature range 137.7–205.4 K. Thermal expansions of these sH hydrate samples were\nalso measured using powder X-ray diffraction. Symmetric stretch vibrational frequencies of CH4 in host–\nwater cages increased because of varying temperature, and the sizes of the host–water cages also\nincreased; variation of CH4 in small cages was less than in larger cages. Comparing the variations of the\nC–H symmetric stretching frequencies of CH4 in gas hydrates with varying pressure and temperature,\nwe suggest that the observed trend is caused by thermal vibrations of the CH4 molecule in water cages.","subitem_description_language":"en","subitem_description_type":"Abstract"}]},"item_3_publisher_212":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"Royal Society of Chemistry","subitem_publisher_language":"en"}]},"item_3_relation_191":{"attribute_name":"DOI","attribute_value_mlt":[{"subitem_relation_type_id":{"subitem_relation_type_id_text":"10.1039/d0ra02748k","subitem_relation_type_select":"DOI"}}]},"item_3_select_195":{"attribute_name":"著者版フラグ","attribute_value_mlt":[{"subitem_select_item":"publisher","subitem_select_language":"en"}]},"item_access_right":{"attribute_name":"アクセス権","attribute_value_mlt":[{"subitem_access_right":"open access","subitem_access_right_uri":"http://purl.org/coar/access_right/c_abf2"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"Go Fuseya","creatorNameLang":"en"}]},{"creatorNames":[{"creatorName":"Satoshi Takeya","creatorNameLang":"en"}]},{"creatorNames":[{"creatorName":"Akihiro Hachikubo","creatorNameLang":"en"}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_access","date":[{"dateType":"Available","dateValue":"2023-04-17"}],"filename":"d0ra02748k.pdf","filesize":[{"value":"708 KB"}],"format":"application/pdf","mimetype":"application/pdf","url":{"url":"https://kitami-it.repo.nii.ac.jp/record/2000408/files/d0ra02748k.pdf"},"version_id":"f1adf13a-fcfd-47ce-a348-cb5fa7c0736f"}]},"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":"Effect of temperature and large guest molecules on the C–H symmetric stretching vibrational frequencies of methane in structure H and I clathrate hydrates","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Effect of temperature and large guest molecules on the C–H symmetric stretching vibrational frequencies of methane in structure H and I clathrate hydrates","subitem_title_language":"en"}]},"item_type_id":"3","owner":"15","path":["1"],"pubdate":{"attribute_name":"PubDate","attribute_value":"2023-04-17"},"publish_date":"2023-04-17","publish_status":"0","recid":"2000408","relation_version_is_last":true,"title":["Effect of temperature and large guest molecules on the C–H symmetric stretching vibrational frequencies of methane in structure H and I clathrate hydrates"],"weko_creator_id":"15","weko_shared_id":-1},"updated":"2023-04-17T01:45:03.803412+00:00"}
