Implication

This research expands tests of aromaticity to include charged and heterocyclic rings, suggesting new analytical methods.

Abstract

Aromaticity is a pivotal concept in chemistry arising from electron delocalization in closed-loop systems that confers extra energetic stabilization. Its direct observation is not possible, making its quantification challenging. To...
