Abstract

A reinvestigation of the k∼0 infrared and Raman active lattice modes of BaN6 crystals is reported. The symmetry species of the Raman active modes were determined unequivocally by oriented single crystal laser excited Raman spectroscopy. A new band at 40 cm-1 was resolved and a number of symmetry reassignments were made. The results are in essential agreement with the space group P21/m-C2h2 for the crystal. The transmission far infrared spectra of polycrystalline BaN6 and SrN6 were measured between 20 to 300 cm-1 and compared with the reflection spectrum of BaN6 reported in the previous study.
