摘要: 由强场静态13C煤谱可以获得与低场魔角旋转高分辨谱相同的fa,从而避免了样品的快速旋转的要求,同时得到了高灵敏度。

关键词: 煤的NMR, 煤的芳香性

Abstract: The aromaticities (fa) of coals measured at high magnetic field via static 13C CP spectra are consistent with those measured at low field by means of high resolution 13C CPMAS. Therefore, the demand for fast sample spining was avoided while high NMR detective sensitivity was maintained at high field.

Key words: NMR of coals, Aromaticity of coals
