The spectral properties of 1,6,7,12,13,18-hexaazatrinaphthylene (HATN) and a number of related compounds are modeled using density functional theory, B3LP The calculations predict the frequencies with mean absolute deviation of 6cm(-1) and there is little improvement on going to basis sets larger than 631 G(d). The substituent effects on the observed spectra are modeled effectively in both frequency shifts and relative intensities. The electronic properties may be predicted using TD-DFT and these are in very good agreement, in terms of transition energies and intensities, with the experimental data. (C) 2008 Elsevier B.V.
