摘要：
We report thermochemical properties of small titanium carbide clusters of mixed stoichiometric ratio TixCy (x,y = 1-4). The molecular data used to set up the thermodynamic functions, which are consistent with the JANAF thermochemical data compilation, are computed by density functional techniques. Equilibrium structure parameters, energies, selected harmonic vibrational wave numbers of energetically low-lying, fully characterised minima are presented along with corresponding absorption coefficients. Thereby, results of species previously not reported in the literature are included in this study. (C) 2014 Elsevier B.V. All rights reserved.
