SOURCE: The polynomial coefficients for heat capacity and entropy are from A. Burcat and B. McBride (1993) 1994 Ideal Gas Thermodynamic Data for Combustion and Air-Pollution Use. Technion Report TAE 697. The enthalpy was chosen as an optimization variable. After further review its value was fixed at that given by J. Horiuchi, T. Yano, and K. Kanai, Shokubai 7, 8 (1951).
