Abstract
The dipole moments, diamagnetic susceptibilities, chemical shifts of the 1H, 13C, and 14N nuclei, and the energies of the lowest singlet-singlet transitions of aza-substituted thiophenes and benzo[b]thiophenes were calculated within the framework of the bonded variant of perturbation theory by the Pariser-Parr-Pople (PPP) method. A scale of aromatic character of the investigated class of compounds is given on the basis of the current distributions found.
