Abstract

The dielectric function of the IR nonlinear optical crystal BaTeMo₂O₉ is obtained by performing a Kramers-Kronig transformation from the measured infrared reflectivity. With the assistant of first principle calculation, the phonon modes are assigned, which is fundamental to confirming the SOJT distortions.
