Abstract

We calculate in this work the specific heat CVI using the predictions of an Ising model for the NH 4 Br crystal (T C =234 K, P=0). Our calculated CVI values are in good agreement with the experimentally observed CP data from the literature. This shows that the observed behavior of NH 4 Br can be described adequately in the lattice region under an Ising model studied here.
