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.

Notes

1From Ovcharenko and Kuzyakov, 1966; rotational analyses of a few additional subbands reported by Pandey, Upadhya, et al., 1971.
2A0 = +3.772 [or A0= -2.729 Verma, 1964].
3D1 = 3.90E-7.
4The origins refer to the zero-point of the Hill-Van Vleck expression for the upper state and to the hypothetical J"=0 levels in the lower state.
5Corrected using calculated head-origin separations Ovcharenko and Kuzyakov, 1962.
6Average values of Ovcharenko, Tunitskii, et al., 1960 and Rai, Singh, et al., 1974. See also Cordes and Gehrke, 1966, Mishra and Khanna, 1969.
7Franck-Condon factors Singh and Dube, 1971.
8D1 = 1.9E-7.
9Av= +207.21 - 0.32 v; small J dependent terms have been determined for v=5...10 Singhal and Verma, 1971.
10Lambda-type doubling Deltav(2Pi1/2) = 0.005(J+1/2) Singhal and Verma, 1971, Rai, Singh, et al., 1974.
