  The thermodynamics and dynamics of a one dimensional dimer-forming anharmonic
model is studied in the classical limit. This model mimics the behavior of
materials with a Peierls instability. Specific heat, correlation length, and
order parameter are calculated three ways: (a) by mean field approximation, (b)
by numerical molecular dynamics simulation, and (c) by an exact transfer matrix
method. The single-particle spectrum (velocity-velocity correlation function)
is found numerically and in mean field theory.
