翻訳と辞書　辞書検索 [ 開発暫定版 ] スポンサード リンク Nuclear Overhauser effect ： ウィキペディア英語版 Nuclear Overhauser effect The nuclear Overhauser effect (NOE) is the transfer of nuclear spin polarization from one spin bath to another spin bath via cross-relaxation. It is a common phenomenon observed by nuclear magnetic resonance spectroscopy. ==History== The theoretical basis for the NOE was described and experimentally verified by Anderson and Freeman in 1962. The NOE is an extension of the seminal work of American physicist Albert Overhauser who in 1953 proposed that nuclear spin polarization could be enhanced by the microwave irradiation of the conduction electrons in certain metals. The general Overhauser effect was first demonstrated experimentally by T. R. Carver and C. P. Slichter, also in 1953. Another early explanation and experimental observation of the NOE was by Kaiser in 1963 in an NMR experiment where the spin polarization was transferred from one population of nuclear spins to another, rather than from electron spins to nuclear spins. However, the theoretical basis and the applicable Solomon equations〔(The Solomon Equations and NOE ). chem.iitm.ac.in〕 had already been published by Ionel Solomon in 1955. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Nuclear Overhauser effect」の詳細全文を読む スポンサード リンク 翻訳と辞書 : 翻訳のためのインターネットリソース Copyright(C) kotoba.ne.jp 1997-2016.
