The structure, the vibrational frequencies and the normal modes of C6ff are calculated with an upgraded QCFF/PI semiempirical quantum chemical method. We use a configuration interaction wavefunction expanded on 400 determinants (all the one-to six-electron excitations in the space spanned by the tri

Properties associated with the infrared, Rayleigh, and Raman spectra of the CO 3 molecule are calculated by the Hartree-Fock and MΓΈller-Plesset perturbation theory methods. Vibrational frequencies and infrared activities are found to be in agreement with the experiment and previous calculations. The
