Abstract
Lattice dynamical calculations have been carried out in the cubic and ortho rhombic phases of the negative thermal expansion compound ZrW2O8. The phono n density of states, thermal expansion, specific heat and bulk modulus have been calculated. The calculations are in good agreement with the available experimental data.
