Induced magnetic fields in aromatic [n]-annulenes-interpretation of NICS tensor components

, 2004
The components of nucleus-independent chemical shift (NICS) tensors for D[nh]n-annulenes are discussed as indexes of the aromatic character of electronic [pi] systems.

py.Aroma: An Intuitive Graphical User Interface for Diverse Aromaticity Analyses

Chemistry
The nucleus-independent chemical shift (NICS) criterion plays a significant role in evaluating (anti-)aromaticity. While being readily accessible even for non-computational chemists, adding ghost atoms for multi-points NICS evaluations poses a ...

Nucleus-Independent Chemical Shifts (NICS):  Distance Dependence and Revised Criteria for Aromaticity and Antiaromaticity

, 2016
Nucleus-independent chemical shifts (NICS) have been used extensively for the identification of aromaticity properties of molecules, ions, intermediates, and transition states since their introduction in 1996 by Schleyer et al.
