title: Hess-Schaad group additivity type model predicts superaromaticity.
abstract: The classical Hess-Schaad reference state and group additivity (GA) model has been adapted to evaluate the resonance energies of several polycyclic aromatic hydrocarbons (PAHs). It was found that benzene is the least stable species in this series, and hence, claims that the concept of superaromaticity is dead are overestimated.
