Gas Phase Heat Capacity (Shomate Equation)

Cp° = A + B*t + C*t2 + D*t3 + E/t2
H° − H°298.15= A*t + B*t2/2 + C*t3/3 + D*t4/4 − E/t + F − H
S° = A*ln(t) + B*t + C*t2/2 + D*t3/3 − E/(2*t2) + G
    Cp = heat capacity (J/mol*K)
    H° = standard enthalpy (kJ/mol)
    S° = standard entropy (J/mol*K)
    t = temperature (K) / 1000.

1Lambda-type doubling Deltanuef = +0.0010J(J+1).
2From bandheads, taking into account head-origin separations.
3Slight modification of the analysis of the 1-1 band in Woods, 1943.
40-0 sequence only. Constants recalculated assuming that the lower state is X 1Sigma+.
5From a partial rotational analysis, assuming that the lower state is X 1Sigma+.
6Microwave sp. 8
