Sažetak

The aromaticity of some bicyclic heterocycles is discussed
with the aid of the configuration analysis of the expansion coefficient
matrices and the similarity analysis of the density matrices.
The iso-it-electronic [9] annulenyl anion is taken as the aromatic
reference compound for all the heterocyclic compounds considered.
The restflts are compared with · those previously obtained from
considerations of energy. In addition the question is posed whether
the sub-structures display aromatic features.
