Despite the significant difference in charge values acquired using different methods for the molecules, the qualitative charge distribution character of the rings is independent of the calculation methods. The distinct difference in electronegativity makes B atoms and N atoms respectively carry evident positive and negative charges in carborazine and borazine. Furthermore, the charge of the C atoms in the carborazine is close to that of the C atoms in benzene, indicating that substitution of two B and two N atoms into benzene does not prominently affect charged state of the remaining C atoms. It can also be seen that the charge difference between B and N atoms in the carborazine is much smaller than that in the borazine, which clearly demonstrates that introducing a C atom between B and N atoms can greatly balance the charge distribution on the ring.
