The model uses eleven adjustable parameters (three inter molecular and eight intramolecular ones) to calculate the frequencies of 45 lattice modes and 24 components of internal modes. Good agreement with recent Raman and infrared studies is obtained. All the symmetry types of the observed modes are identified by inspection of the calculated eigenvectors.
