The phase transition pressure and volume collapse of SrTe have been studied. A three body interaction potential (TBIP) model is developed to study the high pressure phase transition of present compound having NaCl (B1) structure at room temperature. This model includes the long range Columbic, three body interaction forces, short range overlap forces operative up to next nearest neighbors and zero point energy effects.  It is found that the inclusion of zero point energy effects has improved the results.

Keywords: Phase transition, volume collapse, three body interaction and zero point energy.
