ABSTRACTIn this paper, the vibrational FT-Raman spectra obtained at different anodic potentials chosen in the oxidation and reduction branches of the voltamperometric waves of two α,α'-sexithiophenes end capped with n-hexyl and n-thiohexyl groups are investigated. In order to analyze the evolution of the atomic charges and bonth lengths on going from the neutral to the doped species some theoretical calculations have been carried out.

The effect of pressure on DL-alanine has been studied by X-ray powder diffraction (up to 8.3 GPa), single-crystal X-ray diffraction and Raman spectroscopy (up to ∼ 6 GPa). No structural phase transitions have been observed. At ∼ 1.5–2 GPa, cell parameters b and c become accidentally equal to each other, but the space-group symmetry does not change. There is no phase transition between 1.7 and 2.3 GPa, contrary to what has been reported earlier [Belo et al. (2010). Vibr. Spectrosc. 54, 107–111]. The presence of the second phase transition, which was claimed to appear within the pressure range from 6.0 to 7.3 GPa (Belo et al., 2010), is also argued. The changes in the Raman spectra have been shown to be continuous in all the pressure ranges studied.
