翻訳と辞書　辞書検索 [ 開発暫定版 ] スポンサード リンク Gradient enhanced NMR spectroscopy ： ウィキペディア英語版 Gradient enhanced NMR spectroscopy Gradient enhanced NMR is a method for obtaining high resolution nuclear magnetic resonance spectra without the need for ''phase cycling''. Gradient methodology is used extensively for two purposes, either rephasing (selection) or dephasing (elimination) of a particular magnetization transfer pathway. It includes the application of magnetic field gradient pulses to select specific coherences. By using actively shielded gradients, a gradient pulse is applied during the evolution period of the selected coherence to dephase the transverse magnetization and another gradient pulse refocuses the desired coherences remaining during the acquisition period. ==Advantages== *Significant reduction in measuring time *Reduced T1 artifacts *Elimination of phase cycling and difference methods *Possibility for three and four-quantum editing *The ability to detect resonances at the same chemical shift as a strong solvent resonance 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「Gradient enhanced NMR spectroscopy」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.
