The polarized infrared absorption spectra of alpha -sexithienyl single crystal show the Davydov splitting of some intramolecular ungerade phonons. They are analyzed into details considering the perturbation on the molecular force constants due to the solid state interactions within the unit cell. The proposed model allows to identify the effects of the pertubation within the molecular crystal and to estimate the new force constants of the unit cell.

Abstract
The polarized infrared absorption spectra of alpha -sexithienyl single crystal show the Davydov splitting of some intramolecular ungerade phonons. They are analyzed into details considering the perturbation on the molecular force constants due to the solid state interactions within the unit cell. The proposed model allows to identify the effects of the pertubation within the molecular crystal and to estimate the new force constants of the unit cell.File in questo prodotto:
