About this Dataset

Ideal-Gas Thermodynamic Properties For Organic Compounds Containing Up To 7 C, O, Or N Atoms

This data set contains enthalpies of formation, entropies, heat capacities, and thermal enthalpies for about 400 compounds available in the NIST TRC SOURCE database. The enthalpies of formation are computed using the ab initio-based protocol reported in the references below. The other properties are calculated by statistical thermodynamics using the "rigid rotor - harmonic oscillator" approximation. The conformational contributions are found by the Gibbs energy averaging of the properties of the conformers.
