Abstract
The vibrational dynamics of oligomers of selenophene is treated theore tically and the experimental infrared and Raman spectra are studied in order to derive information for the interpretation of the spectra of pristine polyselenophene. Both the electronic and geometrical structur es as well as the dynamical and spectroscopic properties have been cal culated by the semiempirical PM3 method. For the polymer, k=0 phonon f requencies are calculated and a vibrational assignment in proposed.
