The temperature dependence of T_1 of ^\u003c81\u003eBr and ^\u003c121\u003eSb NQR follows the usual T^2 law in the range from 80 to 120 K. T_1 is dominated by fluctuations of the EFG at the Br and Sb nuclei due to lattice vibrations. The T_1 vs. 1/T curves in the region between about 120 and 140 K can be described by exponential curves. The activation energies of motions obtained from these curves are similar to those from proton NMR. The exponential changes of T_1 of Br and Sb NQR are attributable to fluctuations caused by the thermal motion of 4-NH_2PyH cations. Echo signals of Br and Sb NQR in the low temperature phase could not be detected at temperatures higher than 145 and 150 K, respectively, because the S/N ratios became poor owing to the very short T_2. The echo signals could also not be detected at temperatures above T_c because of the short T_2.", "subitem_description_type": "Other"}, {"subitem_description": "論文", "subitem_description_type": "Other"}]}, "item_1617186643794": {"attribute_name": "Publisher", "attribute_value_mlt": [{"subitem_1522300295150": "ja", "subitem_1522300316516": "Verlag der Zeitschrift für Naturforschung"}]}, "item_1617186702042": {"attribute_name": "Language", "attribute_value_mlt": [{"subitem_1551255818386": "eng"}]}, "item_1617186783814": {"attribute_name": "Identifier", "attribute_value_mlt": [{"subitem_identifier_type": "HDL", "subitem_identifier_uri": "http://hdl.handle.net/20.500.12000/40985"}]}, "item_1617186920753": {"attribute_name": "Source Identifier", "attribute_value_mlt": [{"subitem_1522646500366": "ISSN", "subitem_1522646572813": "0932-0784"}]}, "item_1617186941041": {"attribute_name": "Source Title", "attribute_value_mlt": [{"subitem_1522650068558": "ja", "subitem_1522650091861": "Zeitschrift für Naturforschung A"}]}, "item_1617187056579": {"attribute_name": "Bibliographic Information", "attribute_value_mlt": [{"bibliographicIssueDates": {"bibliographicIssueDate": "2002-07-01", "bibliographicIssueDateType": "Issued"}, "bibliographicIssueNumber": "6-7", "bibliographicPageEnd": "472", "bibliographicPageStart": "469", "bibliographicVolumeNumber": "57"}]}, "item_1617258105262": {"attribute_name": "Resource Type", "attribute_value_mlt": [{"resourcetype": "journal article", "resourceuri": "http://purl.org/coar/resource_type/c_6501"}]}, "item_1617265215918": {"attribute_name": "Version Type", "attribute_value_mlt": [{"subitem_1522305645492": "VoR", "subitem_1600292170262": "http://purl.org/coar/version/c_970fb48d4fbd8a85"}]}, "item_1617353299429": {"attribute_name": "Relation", "attribute_value_mlt": [{"subitem_1522306287251": {"subitem_1522306382014": "DOI", "subitem_1522306436033": "https://doi.org/10.1515/zna-2002-6-733"}}, {"subitem_1522306287251": {"subitem_1522306382014": "DOI", "subitem_1522306436033": "info:doi/10.1515/zna-2002-6-733"}}]}, "item_1617605131499": {"attribute_name": "File", "attribute_type": "file", "attribute_value_mlt": [{"accessrole": "open_access", "download_preview_message": "", "file_order": 0, "filename": "vol57no6p469.pdf", "future_date_message": "", "is_thumbnail": false, "mimetype": "", "size": 0, "url": {"objectType": "fulltext", "url": "https://u-ryukyu.repo.nii.ac.jp/record/2009694/files/vol57no6p469.pdf"}, "version_id": "e84b4649-56ef-423c-9729-0c0fed33cc8d"}]}, "item_title": "Bromine and Antimony NQR of 4-Aminopyridinium Tetrabromoantimonate(III)", "item_type_id": "15", "owner": "1", "path": ["1642838338003", "1642838406414"], "permalink_uri": "http://hdl.handle.net/20.500.12000/40985", "pubdate": {"attribute_name": "PubDate", "attribute_value": "2018-05-09"}, "publish_date": "2018-05-09", "publish_status": "0", "recid": "2009694", "relation": {}, "relation_version_is_last": true, "title": ["Bromine and Antimony NQR of 4-Aminopyridinium Tetrabromoantimonate(III)"], "weko_shared_id": -1}
