We report for the first time lattice phonon Raman spectra of the organic semiconductor alpha-sexithiophene (T6) measured with a Raman microprobe technique. We identify spectroscopically two polymorphs, as expected from available structural diffraction studies. Polarized spectra were recorded for symmetry assignment. A comparison of experimental data with Quasi Harmonic Lattice Dynamics calculations, performed starting from the experimental X-ray structures, is given.

Abstract
We report for the first time lattice phonon Raman spectra of the organic semiconductor alpha-sexithiophene (T6) measured with a Raman microprobe technique. We identify spectroscopically two polymorphs, as expected from available structural diffraction studies. Polarized spectra were recorded for symmetry assignment. A comparison of experimental data with Quasi Harmonic Lattice Dynamics calculations, performed starting from the experimental X-ray structures, is given.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
