Reconsideration of the electroabsorption spectra of the tetracene and pentacene crystals
TL;DR: In this article, the authors used the Hamilton R factors to assess further refinements of the fit and suggested the existence of an additional charge transfer (CT) band in the tetracene spectrum, located at 2.77 eV.

Reconsideration of the electroabsorption spectrum of the anthracene crystal
TL;DR: In this article, a non-linear least squares procedure is applied directly to resolve the electroabsorption spectrum of anthracene into individual bands, and a nonlinear least square procedure is used to determine the number of bands.

Interpretation of cis-hexatriene absorption spectrum. The Duschinsky effect
Piotr Petelenz,Barbara Petelenz +1 more
TL;DR: In this article, the differences between the uv absorption spectra of trans− and cis−hexatriene are interpreted in terms of the coupling between the ground state normal modes in the electronic excited state, i.e., the Duschinsky effect.

Electro-absorption spectrum of tetracene. High field measurements on polycrystalline samples
TL;DR: In this paper, the high energy part of the measured EA spectrum into individual bands exhibits a large second derivative contribution from charge transfer (CT) state, not expected for this geometry of the experiment and texture of the samples.
