30多年来高分辨核磁共振已经成为研究分子结构及动念的有力工具。然而这一成熟的方法的主要缺陷是它只能适用于液体样品。许多情况最感兴趣的是固体样品在其原来状态下的信息。像界面现象和多相催化体系的研究就是要得到结合在固体表面上物质的性质和变化等信息。尽管宽谱线核磁共振技术从核磁共振开始发展时就为一些固体物理学家所重视,并一直 For more than 30 years, high-resolution NMR has become a powerful tool for studying molecular structure and dynamics. However, the main drawback of this mature method is that it can only be applied to liquid samples. In many cases, the most interesting is the information of a solid sample in its original state. Studies such as interfacial phenomena and heterogeneous catalysis systems require information such as the nature and variation of species bound to a solid surface. Although wide-band NMR technology has been valued by some solid state physicists since NMR began, it has been
