  We study the role of charge density-wave fluctuations on the temperature
dependence of Seebeck coefficient in quasi-one dimensional conductors with a
Peierls instability. The description of low-dimensional incommensurate charge
density-wave fluctuations as obtained by a generalized Ginzburg-Landau approach
for arrays of weakly coupled chains is embodied in the numerical solution of
the semi-classical Boltzmann transport equation. The energy and temperature
dependence of the scattering time of electrons on fluctuations can then be
extracted and its influence on the Seebeck coefficient calculated. The
connexion between theory and experiments carried out on molecular conductors is
presented and critically discussed.
