边带全抑制和偶极相移技术在^(13)C固体高分辨核磁共振中的应用

APPLICATION OF TOSS AND DIPOLAR DEPHASING TECHNIQUES TO SOLID-STATE HIGH RESOLUTION NMR

应用交叉极化、魔角旋转、边带金抑制和偶极相移技术,可以从固体^(13)C核磁共振谱中区分出非质子碳的信号。本方法为复杂的天然高分子聚合物,如煤、生油岩干酪根等的结构分析提供了有效的手段。

By using CP, MAS, TOSS, and Dipolar Dephasing Techniques, the nonproto-nated carbons can been distinguished from a solid-state ^(13)C NMR spectra. Themethod presented is an effective tool for determining the amount and type ofindividual carbon atoms in the natural complex polymers, such as coal, kerogenetc.
