2. Electronic absorption spectra of neutral perylene(C(sub 30)H(sub 16), and quaterrylene (C(sub 40)H(sub 20) and their positive and negative ions: Ne matrix-isolation spectrascopy and time-dependent density functional theory calculations

Abstract

The report presents the experimental and theoretical absorption spectra of perylene, terrylene and quaterrylene and their positive and negative ions. The oligorylenes isolated in Ne exhibit bright states in the visible region, which implies possible associations with the diffuse interstellar bands.

Abstract

Research is done on the absorption spectra of neutral pentacene (C22H14) and its radical cation (C22H14(super +)) and anion (C22H14(super -)) isolated in solid Ne, Ar and Kr, which have been calculated from the ultraviolet to the near-infrared. In conclusion, TD-DFT measurements were carried out to assist in the examination for the calculated spectral features of the pentacene ions.
