Abstract

The face centered cubic (FCC) Ti₁₄C₁₃⁺ structure was calculated by applying the intermediate neglect of differential overlap self-consistent field unrestricted Hartree-Fock method (INDO SCF UHF) after proper parametrization. The optimized Ti₁₃C₁₃⁺ structure, derived by removing a Ti atom from the corner of the FCC structure, is significantly more stable (by about 220 kcal/mol) than the one derived by removing a Ti atom from the middle of the face. This result implies that the Ti₈C₁₃⁺ met-car cannot form by photodissociation of six Ti atoms from the middle of the FCC faces. An alternative structure for the Ti₁₄C₁₃⁺ cluster is presented.
