Using a density-functional based algorithm, the full IR and Raman spectra are calculated for the neutral Ti8C12 cluster assuming geometries of T h , T d , D 2d and C3v symmetry. The T h pentagonal dodecahedron is found to be dynamically unstable. The calculated properties of the relaxed structure having C3v symmetry are found to be in excellent agreement with experimental gas phase infrared results, ionization potential and electron affinity measurements. Consequently, the results presented may be used as a reference for further experimental characterization using vibrational spectroscopy.
