Here is discussed nephelauxetic effects of the two REE^3+(aq) series from \u0394H^0_\u03b3 data for the hydration change reaction and the tetrad effect variations of their hydration enthalpies (\u0394H_hyd.) and REE-OH_2 distances. The \u0394H^0_\u03b3 data combined with those data for solution of REE(ES)_3\u30fb9(H_2O) with ES = C_2H_5SO_4^- reported previously, suggest that Racah (E^1 and E^3) parameters for light REE^3+ like Nd^3+ decrease in the following order:[REE(H_2O)_9]^3+(aq)\u003eREE(ES)_3\u30fb9(H_2O)\u003e [REE(H_2O)_8]^3+(aq). The average REE^3+-OH_2 distance also decreases in this order. Hence this is a nephelauxetic series that Racah parameters are reduced with decreasing REE^3+-OH_2 distance. The Racah parameters for [REE(H_2O)_9]^3+(aq) series are fairly large and comparable with those of gaseous free REE^3+. No significant tetrad effect is expected in its series variation of (-\u0394H_hyd.). By contrast, [REE(H_2O)8]^3+(aq) series has significantly smaller Racah parameters than gaseous free REE^3+, and a convex tetrad effect is expected in the series variation of (-\u0394H_hyd.). Since (-\u0394H_hyd.). of [REE(H_2O_8)]^3+(aq) in heavy REE series is fitted to a linear function of the reciprocal of observed REE-OH_2 disrance in REECl_3 solution, this relation has been extended to light REE series, and a similar relation for [REE(H_2O)_9]^3+(aq) in light REE series has also been determined from our thermodynamic mixture model and observed REE-OH_2 distances in REECL_3 (REE=La, Pr and Nd) solutions. The reciprocal of REE-OH_2 distance in [REE(H_2O)_8]^3+(aq), when plotted against the atomic number of REE, indicates a small convex tetrad effect whereas such an effect is absent in [REE(H_2O)_9]^3+(aq) , in accordance with their nephelauxetic effects. Interestingly, (-\u0394H_hyd.) of [REE(H_2O)_9]^3+(aq) satisfies a linear function of 1/(REE-OH_2), and at the same time, the series variations of both (-\u0394H_hyd.) and 1/(REE-OH_2) exhibit small convex tetrad effects when plotted against the atomic number of REE. This is analogous to the relationship between the lattice enthalpy of REEO_1.5(cubic) and REE-O distance. The property of (-\u0394H_hyd.) and the lattice enthalpy of REEO_1.5 can be understood from the viewpoints: i) the existence of REE(III) cluster with the equilibrium configuration having the minimum energy by itself, and ii) the classical limit in quantum-chemical energetics where Planck\u2019s constant (h) equals zero. It is emphatically noted that the observed tetrad effects and RSPET can complement the classical ion model with a tactic by which internal structures of the real REE^3+ ions are legitimately introduced into our thermodynamic discussion.", "subitem_description_type": "Abstract"}]}, "item_9_description_5": {"attribute_name": "\u5185\u5bb9\u8a18\u8ff0", "attribute_value_mlt": [{"subitem_description": "\u56fd\u7acb\u60c5\u5831\u5b66\u7814\u7a76\u6240\u3067\u96fb\u5b50\u5316\u3057\u305f\u30b3\u30f3\u30c6\u30f3\u30c4\u3092\u4f7f\u7528\u3057\u3066\u3044\u308b\u3002", "subitem_description_type": "Other"}]}, "item_9_identifier_60": {"attribute_name": "URI", "attribute_value_mlt": [{"subitem_identifier_type": "HDL", "subitem_identifier_uri": "http://hdl.handle.net/2237/9423"}]}, "item_9_identifier_registration": {"attribute_name": "ID\u767b\u9332", "attribute_value_mlt": [{"subitem_identifier_reg_text": "10.18999/joueps.53.51", "subitem_identifier_reg_type": "JaLC"}]}, "item_9_publisher_32": {"attribute_name": "\u51fa\u7248\u8005", "attribute_value_mlt": [{"subitem_publisher": "Dept. of Earth and Planetary Sciences, Nagoya University"}]}, "item_9_select_15": {"attribute_name": "\u8457\u8005\u7248\u30d5\u30e9\u30b0", "attribute_value_mlt": [{"subitem_select_item": "publisher"}]}, "item_9_source_id_7": {"attribute_name": "ISSN\uff08print\uff09", "attribute_value_mlt": [{"subitem_source_identifier": "0919-875X", "subitem_source_identifier_type": "ISSN"}]}, "item_9_text_14": {"attribute_name": "\u30d5\u30a9\u30fc\u30de\u30c3\u30c8", "attribute_value_mlt": [{"subitem_text_value": "application/pdf"}]}, "item_creator": {"attribute_name": "\u8457\u8005", "attribute_type": "creator", "attribute_value_mlt": [{"creatorNames": [{"creatorName": "KAWABE, Iwao"}], "nameIdentifiers": [{"nameIdentifier": "21843", "nameIdentifierScheme": "WEKO"}]}, {"creatorNames": [{"creatorName": "TAKAHASHI, Takafumi"}], "nameIdentifiers": [{"nameIdentifier": "21844", "nameIdentifierScheme": "WEKO"}]}, {"creatorNames": [{"creatorName": "TANAKA, Kazuya"}], "nameIdentifiers": [{"nameIdentifier": "21845", "nameIdentifierScheme": "WEKO"}]}, {"creatorNames": [{"creatorName": "OHTA, Atsuyuki"}], "nameIdentifiers": [{"nameIdentifier": "21846", "nameIdentifierScheme": "WEKO"}]}]}, "item_files": {"attribute_name": "\u30d5\u30a1\u30a4\u30eb\u60c5\u5831", "attribute_type": "file", "attribute_value_mlt": [{"accessrole": "open_date", "date": [{"dateType": "Available", "dateValue": "2018-02-19"}], "displaytype": "detail", "download_preview_message": "", "file_order": 0, "filename": "KJ00004741140.pdf", "filesize": [{"value": "1.6 MB"}], "format": "application/pdf", "future_date_message": "", "is_thumbnail": false, "licensetype": "license_free", "mimetype": "application/pdf", "size": 1600000.0, "url": {"label": "KJ00004741140.pdf", "url": "https://nagoya.repo.nii.ac.jp/record/7705/files/KJ00004741140.pdf"}, "version_id": "10d9539c-835a-4d3b-853c-0e41b0b2a345"}]}, "item_language": {"attribute_name": "\u8a00\u8a9e", "attribute_value_mlt": [{"subitem_language": "eng"}]}, "item_resource_type": {"attribute_name": "\u8cc7\u6e90\u30bf\u30a4\u30d7", "attribute_value_mlt": [{"resourcetype": "departmental bulletin paper", "resourceuri": "http://purl.org/coar/resource_type/c_6501"}]}, "item_title": "Hydration change reaction of light REE^3+(aq) series-II:Contrasting nephelauxetic effects between hydrated [REE(H_2O)_9]^3+ and [REE(H_2O)_8]^3+ series and the tetrad effects in their hydration enthalpies and REE-OH_2 distances", "item_titles": {"attribute_name": "\u30bf\u30a4\u30c8\u30eb", "attribute_value_mlt": [{"subitem_title": "Hydration change reaction of light REE^3+(aq) series-II:Contrasting nephelauxetic effects between hydrated [REE(H_2O)_9]^3+ and [REE(H_2O)_8]^3+ series and the tetrad effects in their hydration enthalpies and REE-OH_2 distances"}]}, "item_type_id": "9", "owner": "1", "path": ["336/337/338/895"], "permalink_uri": "https://doi.org/10.18999/joueps.53.51", "pubdate": {"attribute_name": "\u516c\u958b\u65e5", "attribute_value": "2008-02-19"}, "publish_date": "2008-02-19", "publish_status": "0", "recid": "7705", "relation": {}, "relation_version_is_last": true, "title": ["Hydration change reaction of light REE^3+(aq) series-II:Contrasting nephelauxetic effects between hydrated [REE(H_2O)_9]^3+ and [REE(H_2O)_8]^3+ series and the tetrad effects in their hydration enthalpies and REE-OH_2 distances"], "weko_shared_id": null}
