The approach treats both the intermolecular lattice interactions and internal molecular interactions in a unified manner and leads to calculated values of not only the lattice frequencies but also the crystal field splitting of the internal modes for comparison with experimental spectroscopic data. Eight adjustable parameters(one intramolecular and seven intermolacular ones) to calculate the frequencies of thirty seven lattice and eight components of internal modes. In agreement with RAMAN and IR spectra is obtained, Principal intermolecular interactions are identified.
