  We investigate the integrable higher spin XXZ chain at the Razumov-Stroganov
point. We present a method to evaluate the exact value of the eigenvalue which
is conjectured to correspond to the groundstate of the Hamiltonian for finite
size chain from the Baxter Q operator. This allows us to examine the exact
total energy difference between different number of total sites, from which we
find strong evidence for the absence of finite size correction to the
groundstate energy.
