用高分辨核磁共振研究被吸附在固体表面的分子表明其共振频率与自由分子不同。这种变化表示在吸附过程中,分子中电子分布受到干扰,特别是当分子对固体表面有优先取向的情况下,各种关能团中核磁共振的频率变化更明显。对被吸附在各种孔结构活性炭中的汽油和烃口的NMR研究揭示出被吸附分子以两种状态存在。根据被吸附的链状烷烃中化学环 Studying molecules adsorbed on a solid surface using high-resolution NMR shows that the resonance frequency is different from that of a free molecule. This change indicates that the electron distribution in the molecule is disturbed during the adsorption process, especially when the molecule has a preferential orientation on the solid surface, and the frequency of the nuclear magnetic resonance in various energy groups changes more obviously. NMR studies of gasoline and hydrocarbon ports adsorbed on various pore structure activated carbons revealed that the adsorbed molecules exist in two states. Depending on the chemistry of the chain alkane being adsorbed
