We calculated the specific heat C-V of ND4Cl under the prediction of an Ising model presented here. Our calculated C (V) agrees with the experimental C (P) data for the multicritical (P = 0.1 MPa) and second order (P = 150 MPa) phase regions in this crystalline system. This agreement is particularly good above T (C) (congruent to 250 K)for the multicritical regime and below T (C) (congruent to 261 K) for the second order phase transition in ND4Cl. This shows that the observed behaviour of ND4Cl can be well described by an Ising model close to the phase transitions considered in this crystalline system.
