'Low and high-frequency vibrational dynamics as a function of structural order in polythiophene'
, Synth. Met. 84 569-570 (1997) doi:
10.1016/s0379-6779(97)80862-4
We report the phonon density of states of intrachain and interchain low-frequency modes in polythiophene. These new results were obtained by inelastic incoherent neutron scattering experiments. Raman, photoluminescence and X-ray diffraction spectra measured on the same samples are also reported. The behaviour of the low and high-frequency modes as a function of the crystallinity and conjugation is discussed.
