Abstract: A lattice dynamical model which includes the effect of three-body interactions (TBI) in the framework of second neighbour rigid shell model (SNTRSM) and second neighbour rigid ion model (SNTRIM) has been developed. The models, thus obtained, have been applied to study the phonon dispersion curves (PDCs) of TiN along the principal symmetry directions. It is found that SNTRSM explains well the phonon anomalies in the experimental PDCs of TiN as compared to SNTRIM and other models.
