摘要/Abstract

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
