Magnetic criteria of aromaticity

This review describes the current state of magnetic criteria of aromaticity. The introduction contains the fundamentals of ring currents in aromatic and antiaromatic systems, followed by a brief description of experimental and computational tools: NMR, diamagnetic susceptibility exaltation, current density analyses (CDA) and nucleus independent chemical shifts (NICS). This is followed by more comprehensive chapters: NMR-focusing on the work of R. Mitchell-NICS and CDA-describing the progress and development of the methods to their current state and presenting some examples of representative work.
