We present FT-Raman and FT-IR spectra of two β-methyl substituted thiophene dimers.
Methylation at β-positions modulates the equilibrium molecular conformation, thus affecting …

We report on the vibrational infrared and Raman spectra of two β-alkyl substituted
bithiophenes with well-defined substitution patterns: the 3, 3′-and the 4, 4′-dimethyl-2 …

We present FT-Raman and FT-IR spectra of neutral α, α′-dimethyl end-capped
oligothiophenes (to six thiophene units) as solid samples and in solution. Gas-phase …

In this paper we report on the vibrational Fourier transform infrared (FT–IR) and Fourier
transform Raman (FT–Raman) spectra of a few donor–acceptor–substituted bi-ter-, and …

We report the FT-IR and FT-Raman spectra of the first members of a series of recently
synthesized cycloalkane end-capped oligothiophenes. Theoretical equilibrium structures …

Ab initio quantum-chemical methods have been used to investigate how the inclusion of
ester groups on polythiophene chains can affect some properties of the polymer. For this …

The structure and vibrational spectroscopy of 2, 5-diiodothiophene have been described for
the first time. The structure is remarkable in that, despite the presence of eight molecules in …

Electronic structure of the ground and excited states of terthiophene was studied
theoretically by means of density functional theory (DFT). In particular, investigations are …

We have studied the FT-IR and FT-Raman spectra of a neutral thiophene-based oligomer in
relation to the effective conjugation length of the π-electrons. The compound has a well …

Molecular structures of a series of 3 '-[1 E-2-(4-R-phenyl) ethenyl]-2, 2 ': 5 ', 2 ''-terthiophenes
have been modeled using ab initio calculations. The potential energy surfaces of three …
