We calculated in this study the Raman frequencies of some lattice modes in the melting region of ammonia solid I. The Raman frequencies of those phonon modes were obtained through the Grüneisen relation using the volume data for the ammonia solid I from the literature. Our calculated Raman frequencies require for comparison the experimental Raman frequencies measured as a function of pressure for some fixed temperatures in the ammonia solid I.
