Description
Summary:The set of three oligothiophenes covalently linked to fullerene was investigated using vibrational spectroscopy combined with DFT (B3LYP/6-31G(d,p)) calculations. The set of three oligothiophenes covalently linked to fullerene was investigated using Raman scattering and the infrared absorption spectroscopies. Additionally, the quantum chemical calculations of the equilibrium geometry and normal mode vibrations of the dyads were performed. It was shown that vibrational spectroscopy can be successfully used for characterization of such complex molecular systems. It was stated that infrared spectra in the region 700–900 cm −1 act as fingerprints for the investigated dyads.
