Thermodynamic properties of diatomic molecules containing platinum (PtH, PtC, PtN and PtO) have been calculated using spectroscopic data and partition function theory. Values of the Gibbs energy (), enthalpy (), entropy () and specific heat capacity at constant pressure () are presented for each species in the temperature range from 100 K to 3000 K. To obtain the most accurate data, anharmonicity, nonrigidity and stretching effects have been incorporated in the calculations. The variation of these properties with temperature is also discussed in terms of different modes of molecular motion.
