title: Dissected nucleus-independent chemical shift analysis of pi-aromaticity and antiaromaticity.
abstract: [structure: see text] Analysis of the basic pi-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.
