稠核芳香化合物分子以及石墨、Bi等晶体物质之反磁磁化率具有显著的方向性。这种反磁性各向异性现象自从K.S.Krishnan等人发现并进行系统地大量的实验工作以来,曾吸引了许多物理学与化学工作者参与此项问题的研究,获得了重要的成果并已成为研究物质结构的磁化学方法的重要的理论基础。至今虽然积累了相当丰富的实验数据,但是不论在理论分析上或是实验材料的综合整理上都还是不尽令人满意的。理论计算工作始自L.Pauling F.London,后来不少人从不同角度和
The visco-magnetic susceptibility of the condensed-core aromatic compound molecules and crystalline materials such as graphite and Bi has remarkable directivity. This anti-magnetic anisotropy has attracted many physicists and chemists involved in the study of this issue since KS Krishnan et al. Discovered and conducted extensive systematic work that has yielded important results and has become a study Material structure of the magnetization method of the important theoretical basis. Although it has accumulated a wealth of experimental data so far, it is still unsatisfactory both in theoretical analysis and in the synthesis of experimental materials. Theoretical calculations began with L. Pauling F. London, and many later came from different perspectives
