A lot of informaiton in interstellar space has been mainly obtained by millimeter-wave astronomical observations, but in millimeter wave region relatively heavy molecules have their rotational transitions.  Observations of small molecules such as hydrides are limited, although they are important to understand the produciton mechanism related hydrogen compounds.  Most of hydrides have rotational transitions in submillimeter-wave or far-infrared region.  Recently, the astronomical observation techniques in submillimeter-wave, far-infrared, and infrared regions are greatly developed, and the observations in these regions become possible.  However, there are a few laboratory data for molecules in these regions.  In the present study, far-infrared and infrared Fourier transform spectroscopy was applied to measure transient molecules of astronomical interest in laboratory and the results were applied to astronomically observed data.\n  The dc discharge cell with multi-reflection system was constructed for far-infrared absorption measurement.  The author applied to observe the pure rotational spectra of the SH, NH2, NHD, and ND2 radicals and the vibration rotaiton spectrum of NH2OH.  The measurement of SH was the first applicaiton of far-infrared Fourier transform spectroscopy to transient molecules, and detection limit of this measurement system was estimated.  About 600 rotational lines of NH2, NHD, ND2 and about 5000 rovibrational lines of NH2OH were observed in high-resolution and wide frequency coverage.  By the anlysis of the observed spectra, precise molecular parameters were obtained.  The information obtained by these measurements is very useful for sub-millimeter and far-infrared astronomical observation.\n  The positive column discharge cell was constructed for infrared emission observation.  The author applied to measure the vibration rotational specta of the CD and 18OH radicals.  By analysis, precise molecular constants in the vibrationally excited states were obtained.  From intensity analysis using Herman-Wallis effect, the vibration transition moment of CH was determined, and applied to determination of column density in infrared astronomical observation.  The observed intensity of 18OH was discussed.\n  Some result of laboratory spectroscopy were applied to astronomical observational results.  The upper limit of column density of SH was estimated from the submillimeter-wave emission spectrum in Orion-KL.  For clarifying the production mechanism of SHn, it is clear that more deep search for SH is necessary.  Using the transition moment of CH in this study, the column density of CH was determined from infrared absorption spectrum in late-type star TX Psc.  The author found that the column density in envelope of C-type late star was almost same as diffuse cloud.  The rotational spectrum of NHD was not found in the published millimeter and submillimeter line survey data in Orion-KL and Sgr B2.","subitem_description_type":"Other"}]},"item_1_description_18":{"attribute_name":"フォーマット","attribute_value_mlt":[{"subitem_description":"application/pdf","subitem_description_type":"Other"}]},"item_1_description_7":{"attribute_name":"学位記番号","attribute_value_mlt":[{"subitem_description":"総研大甲第192号","subitem_description_type":"Other"}]},"item_1_select_14":{"attribute_name":"所蔵","attribute_value_mlt":[{"subitem_select_item":"有"}]},"item_1_select_8":{"attribute_name":"研究科","attribute_value_mlt":[{"subitem_select_item":"数物科学研究科"}]},"item_1_select_9":{"attribute_name":"専攻","attribute_value_mlt":[{"subitem_select_item":"09 天文科学専攻"}]},"item_1_text_10":{"attribute_name":"学位授与年度","attribute_value_mlt":[{"subitem_text_value":"1995"}]},"item_1_version_type_23":{"attribute_name":"著者版フラグ","attribute_value_mlt":[{"subitem_version_resource":"http://purl.org/coar/version/c_ab4af688f83e57aa","subitem_version_type":"AM"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"MORINO, Isamu","creatorNameLang":"en"}],"nameIdentifiers":[{}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2016-02-17"}],"displaytype":"simple","filename":"甲192_要旨.pdf","filesize":[{"value":"205.8 kB"}],"format":"application/pdf","licensetype":"license_11","mimetype":"application/pdf","url":{"label":"要旨・審査要旨 / Abstract, Screening Result","url":"https://ir.soken.ac.jp/record/360/files/甲192_要旨.pdf"},"version_id":"87718da0-ffed-413b-bc20-57549a77d0de"},{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2016-02-17"}],"displaytype":"simple","filename":"甲192_本文.pdf","filesize":[{"value":"13.3 MB"}],"format":"application/pdf","licensetype":"license_11","mimetype":"application/pdf","url":{"label":"本文 / Thesis","url":"https://ir.soken.ac.jp/record/360/files/甲192_本文.pdf"},"version_id":"77a92bd8-49fc-45ac-b81f-035b9633c06e"}]},"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":"thesis","resourceuri":"http://purl.org/coar/resource_type/c_46ec"}]},"item_title":"Far-Infrared and Infrared Spectroscopy of Transient Molecules of Astronomical Interest","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Far-Infrared and Infrared Spectroscopy of Transient Molecules of Astronomical Interest"},{"subitem_title":"Far-Infrared and Infrared Spectroscopy of Transient Molecules of Astronomical Interest","subitem_title_language":"en"}]},"item_type_id":"1","owner":"1","path":["11"],"pubdate":{"attribute_name":"公開日","attribute_value":"2010-02-22"},"publish_date":"2010-02-22","publish_status":"0","recid":"360","relation_version_is_last":true,"title":["Far-Infrared and Infrared Spectroscopy of Transient Molecules of Astronomical Interest"],"weko_creator_id":"1","weko_shared_id":1},"updated":"2023-06-20T14:56:19.822445+00:00"}
