Abstract
In our calculations of lattice vibration, one acoustic and three optical branche s were found to compose the phonon vibrating spectrum. Some isolated modes with frequencies lying outside the continuum branches aise under the defect states. These localized modes result in the sharp peaks in the infrared absorption and Raman spectra.
