Abstract
Ab initio, electron correlated calculations of the dipole moments and static dipole polarizabilities are reported for benzene and ten heteroaromatic molecules: pyridine, 1,2-diazine 1,3-diazine, 1,4-diazine, 1,3,5-triazine, 1,2,4,5-tetrazine, hexazine, borazine, boroxine and phosphabenzene. The results are in reasonable agreement with available experimental data, except for the polarizability anisotropy of s-tetrazine. Aromaticity scales based on polarizabilities are discussed.
