Abstract

A Raman scattering study of the pressure induced phase transition in thallium azide is discussed. The transition appears to be triggered by the softening of a mode at 33 cm^-1, which is shown by a Green's function calculation to be anharmonically coupled to another mode of the same symmetry at 48 cm^-1.
