V. Hernandez et al., DELOCALIZATION LENGTH, ELECTRONIC-PROPERTIES AND VIBRATIONAL-SPECTRA OF NEUTRAL ALPHA,ALPHA'-DIMETHYL END-CAPPED OLIGOTHIOPHENES, Synthetic metals, 76(1-3), 1996, pp. 277-280
We present FT-Raman and FT-IR spectra of neutral alpha,alpha'-dimethyl
end-capped oligothiophenes (to six thiophene units) as solid samples
and in solution. Gas-phase potential to internal rotation of alpha,alp
ha'-dimethylbithiophene has been predicted by ab initio calculations a
t the RHF/6-31G* level, as a model for the theoretical study of the c
onformational flexibility of these molecules.
