The IR spectra of neutral Ti8C12 metallocarbohedryne (Met-Car) and its cation are predicted based on the complete active space self-consistent field (CASSCF) method. The blue shift predicted for the C-C stretching frequency in Ti8 C12+ with respect to neutral Ti8C12 is in agreement with experimental results. The triply degenerate C-C stretching mode splits into doubly and singly degenerate modes as a result of the Ti8C12 Jahn-Teller distortion from Td to D2d symmetry. The splitting is small for...[Show more]
