Analysis of the basic π-aromatic (benzene) and antiaromatic (cyclobutadiene) systems by dissected nucleus-independent chemical shifts (NICS) shows the contrasting diatropic and paratropic effects, but also reveals subtleties and unexpected details.
通过剖析的核独立化学位移（NICS）对基本的π-芳香性（苯）和反芳香性（环丁二烯）体系进行分析，结果显示出相反的抗磁和顺磁效应，但同时也揭示了一些微妙之处和意想不到的细节。
