The ground-state geometries, absorption wavelengths, oscillation strengths for a series of some novel hetarylazoindole derivatives were studied with density functional theory (DFT) and time-dependent density functional theory (TD-DFT). All calculations were carried out with Gaussian03 software package. A comparison of the computed and the experimental data revealed that the most appropriate functional and basis sets are B3LYP, 6-31G(d), 6-31G(d, p), and 6-311G(d, p). An excellent agreement between the experimental and computed data for lambda(max) determinations were observed.
