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 (cal/mol*K)
    H° = standard enthalpy (kcal/mol)
    S° = standard entropy (cal/mol*K)
    t = temperature (K) / 1000.

Notes

1The revised vibrational analysis of the B larrow X1 system by Cordes and Gehrke, 1966 leads to the expression nu = 34937.5 + 386.3(v'+1/2) - 1.36(v'+1/2)2 - 300.8(v"+1/2) + 1.04(v"+1/2)2 Cordes and Gehrke, 1966 and nu00 = 34980.2 Cordes and Gehrke, 1966.
2Diffuse bands (prediss.)
3Tentative rotational analyses Rao and Rao, 1964, Singh and Singh, 1968.

5See Wieland and Newburgh, 1952 for a discussion of this value.
6From an electron impact study of PbCl2 by Hastie, Bloom, et al., 1967, 2 who have also determined the electron affinity of PbCl, E.A. = 1.0 eV.
