Density functional theory calculation is applied to H+·(HCOOH)n (n = 2-5). Geometry optimization of H+·(HCOOH)n (n = 2-5) indicates that stable forms of these clusters are open-chain structures with free OH groups at both ends. In the infrared photodissociation spectra of the n = 2 and n = 3 species, there are two sharp bands in the range of 3400-3700 cm -1. The lower- and higher-frequency bands of them are attributed to the free OH stretching vibrations of the peripheral COOH groups in the E and Z conformations, respectively. The intensity of the higher-frequency band, relative to that of the lower-frequency band, decreases from n = 2 to n = 3. The n = 4 and n = 5 ions exhibit only one sharp band in the same region. This band is assigned to the free OH stretching vibrations of the end COOH groups in the E conformation; the n = 4 and n = 5 ions have the peripheral COOH groups only in the E conformation. We observe infrared photodissociation spectra of H+·(HCOOH)n (n = 6, 7) in the 3500-3600 cm -1 region. The absence of any free OH band for n = 7 shows that both ends of chain structures of n = 7 are terminated by cyclic dimers. Infrared photodissociation spectra of H+·(CH3COOH) n (n = 2-5) are also examined in the 3000-3700 cm-1 region. Resemblance of the spectra of H+·(CH 3COOH)n to those of H+·(HCOOH) n suggests that the acetic acid clusters have structures that are similar to those of the formic acid clusters; the intermolecular network is formed only by the COOH groups.","subitem_description_language":"en"},{"subitem_description":"This is a preprint of an article published by American Chemical Society in Journal of Physical Chemistry A, 2003, available online: http://pubs.acs.org/doi/abs/10.1021/jp030475n","subitem_description_type":"Other"}]},"item_1617186643794":{"attribute_name":"Publisher","attribute_value_mlt":[{"subitem_publisher":"American Chemical Society"}]},"item_1617186702042":{"attribute_name":"Language","attribute_value_mlt":[{"subitem_language":"eng"}]},"item_1617186920753":{"attribute_name":"Source Identifier","attribute_value_mlt":[{"subitem_source_identifier":"1089-5639","subitem_source_identifier_type":"ISSN"}]},"item_1617187024783":{"attribute_name":"Page Start","attribute_value_mlt":[{"subitem_start_page":"11319"}]},"item_1617187056579":{"attribute_name":"Bibliographic Information","attribute_value_mlt":[{"bibliographicIssueDates":{"bibliographicIssueDate":"2003-12-25","bibliographicIssueDateType":"Issued"},"bibliographicIssueNumber":"51","bibliographicPageEnd":"11323","bibliographicPageStart":"11319","bibliographicVolumeNumber":"107","bibliographic_titles":[{"bibliographic_title":"Journal of Physical Chemistry A "},{"bibliographic_title":"Journal of Physical Chemistry A "}]}]},"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_version_resource":"http://purl.org/coar/version/c_b1a7d7d4d402bcce","subitem_version_type":"AO"}]},"item_1617353299429":{"attribute_name":"Relation","attribute_value_mlt":[{"subitem_relation_type":"isVersionOf","subitem_relation_type_id":{"subitem_relation_type_id_text":"http://dx.doi.org/10.1021/jp030475n","subitem_relation_type_select":"DOI"}},{"subitem_relation_type_id":{"subitem_relation_type_id_text":"10.1021/jp030475n","subitem_relation_type_select":"DOI"}}]},"item_1617605131499":{"attribute_name":"File","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_access","date":[{"dateType":"Available","dateValue":"2023-03-18"}],"displaytype":"simple","filename":"JPhysChemA_2003_107_11319.pdf","filesize":[{"value":"279.4 KB"}],"mimetype":"application/pdf","url":{"objectType":"fulltext","url":"https://hiroshima.repo.nii.ac.jp/record/2007497/files/JPhysChemA_2003_107_11319.pdf"},"version_id":"9a337986-ad6b-4515-825f-74fc3636e418"}]},"item_1732771732025":{"attribute_name":"旧ID","attribute_value":"14733"},"item_title":"Infrared Photodissociation Spectroscopy of Protonated Formic Acid and Acetic Acid Clusters","item_type_id":"40003","owner":"41","path":["1730444907710"],"pubdate":{"attribute_name":"PubDate","attribute_value":"2023-03-18"},"publish_date":"2023-03-18","publish_status":"0","recid":"2007497","relation_version_is_last":true,"title":["Infrared Photodissociation Spectroscopy of Protonated Formic Acid and Acetic Acid Clusters"],"weko_creator_id":"41","weko_shared_id":-1},"updated":"2025-02-21T10:05:42.227437+00:00"}
