Résumé

In the trichalcogenide family of compounds Zr1-xHfxS3 there is a frequency range where the optic modes are expected to be describable by a simple one-dimensional model. It is shown that the disorder-induced linewidth in the relevant frequency range could be consistent with theoretical calculations for a simple diatomic chain model. The vibrations involved are along the chain direction and are of B(g) type. All the B(g) modes of this family of compounds are also here unequivocally identified.
