IR and Raman spectra for sodium bifluoride containing 2%, 11% and x80% DFZ are presented. Changes in the DFS u2 and q IR bands with deuteration are related to coupting between Iike oscillators or states. Raman assignments are made for the HFZ ~1 and lattice Librational (Eg) modes. \* For a review of

โฆ Synopsis
We present computations of the structure and of the vibrational frequencies of the cubane molecule at the Hartree-Fock and the MP2 levels of theory with the 6-311G * basis set. We also present empirical correction factors for all computational data. The agreement between the corrected theoretical and the experimental data is satisfactory.

## Abstract Raman spectra of crystalline pentachloroaniline (PCA) have been measured. The infrared spectra have also been recorded for solid and solutions in CCl~4~ between 4000โ200 cm^โ1^. An assignment of the observed frequencies has been proposed for a __C__~s~ molecular symmetry based on relate
We have used an approximate first-principles method together with a bond-polarizability model to calculate theoretical Raman spectra for the orthorhombic (O), tetragonal (T), and rhombohedral (R) phases of pressure-polymerized C 60 solid. We have also calculated Raman spectra for a sequence of C 60
