For each reaction species, the thermodynamic functions specific heat, enthalpy and entropy as
functions of temperature are given in the form of least squares coefficients as follows:

Cp/R = A1 + A2T + A3T² + A4T³ + A5T⁴

H/(R*T) = A1 + A2T/2 + A3T²/3 + A4T³/4 + A5T⁴/5 + A6/T

S/R = A1lnT + A2T + A3T²/2 + A4T³/3 + A5T⁴/4 + A7

or

S/R = A1lnT + A2T + A3T²/2 + A4T³/3 + A5T⁴/4 + A7 - lnp

For each species, two sets of coefficients are included for two adjecent temperature intervals, 273 to 1,000 [K]
and 1,000 to 5,000 [K]. The data have been constrained to be equal at 1,000 [K].

Also,

U = H - p*v*MW or U = H - R*T

G = H - S*T

and

u = h - p*v or u = h - R*T/MW

g = h - s*T
