Abstract
The first- and second-order Raman phonon spectra of were measured in phase IV using Raman and resonance-Raman scattering. Twelve Raman active phonons were resolved at 32, 35.5, 42, 52, 72, 90, 110, 115, 121, 189, 200.5, and and correlated to the phonon spectrum of in phase I. The highest frequency longitudinal optical mode is
