 Title: LATTICE DYNAMICS OF MOLECULAR CRYSTALS. II. CYANOGEN BROMIDE. Creators: Bandy, Alan; Bates, John B.; Lippincott, Ellis R.; McMurry, H. L. Issue Date: 1969 Publisher: Ohio State University Abstract: The results of a measurement of the polarized Raman spectrum of single crystal CNBr at $300^{\circ} K$ will be described. Using the procedures outlined in I above, we have calculated the crystal vibrations for $k=0$ and have refined a simple valence force potential based on all the currently known optical modes. The dispersion curves for the [100] and [001] directions were calculated from the optically'' refined valence force field. The results of the dispersion calculations and the effects of including long-range coulomb forces to the valence force field will be described.
