气体分子在固体表面上的吸附以及催化剂的活性中心一直是人们感兴趣的问题,这对在分子水平上研究催化机理具有重要的意义.气体分子吸附到固体表面上以后,由于存在多种各向异性相互作用,分子运动受阻,得到的谱线介于固体谱和液体谱之间,为宽线谱.通过对宽线谱线型的分析、弛像时间及化学位移屏蔽张量的测量,可以在一定程度上反映吸附分 The adsorption of gas molecules on the solid surface and the active center of the catalyst have always been of interest, which is of great significance for studying the catalytic mechanism at the molecular level.After the adsorption of the gas molecules onto the solid surface, Heterosexual interaction, molecular movement blocked, the spectrum was obtained between the solid spectrum and the liquid spectrum, wide line spectrum.By analyzing the broad line spectral type, relaxation time and chemical shift shielding tensor measurement, you can To a certain extent, reflect the adsorption points
