Key Points

This research aims to evaluate the structural indices of (anti)aromaticity in polycyclic hydrocarbons, particularly in triplet states.
Reparametrization of the harmonic oscillator model of aromaticity (HOMA)
Testing derived HOMER on monocycles
Assessment of (anti)aromaticity in polycyclic compounds
HOMER demonstrates improved accuracy over HOMA for excited states
Clear differentiation of (anti)aromatic character in polycyclic compounds

Implication

The analysis demonstrates (anti)aromaticity indices in polycyclic hydrocarbons, indicating improvements in assessment methods.

Abstract

The harmonic oscillator model of aromaticity (HOMA) has recently been reparametrized for assessing (anti)aromaticity of excited states. The derived HOMER has been tested on monocycles. In polycyclic compounds, the spin...
