| Abstract: | A Peierls distortion incommensurate with the lattice constant is considered in the Fröhlich model of a linear conductor. A prediction for the correlation length of the distortion is obtained using a Ginzburg-Landau expansion of the free energy for temperatures well belowT
p
, the mean field Peierls transition temperature. The correlation length is found to be strongly increasing at aboutT
