Thermodynamic Property Data
- Description
-
The representative thermodynamic properties such as standard enthalpy (H0), standard entropy (S0), standard Gibbs free energy (G0), and heat capacities (Cv and Cp at constant volume and pressure, respectively) have been calculated by using ab initio theoretical methods and fitting equations.
-
Prior to the thermodynamic property data, some fundamental physical property data for electron affinity (EA), ionization potential (IP), and polarizability (ɑ) are presented with basic information on a target compound.
