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)

Notes

1Λ-type doubling |Δv| = 0.1275J(J+l) - 0.54E-4J2(J+1)2.
2Sequence of nearly undegraded bands; the origins of the 1-1 and 2-2 bands are at 61554.5 and 61560.7 cm-1, respectively.
3A0 = -115.71, A1 = -115.20; see Rostas, Cossart, et al., 1974 who give also centrifugal distortion corrections AD as well as estimated spin-spin and second-order spin-orbit parameters.
4Estimated using isotope relations.
5For Λ-doubling constants see Rostas, Cossart, et al., 1974.
6B1 = 7.5492. No emission has been observed from v=1 of PH, probably owing to weak predissociation by the repulsive 5Σ- state arising from ground state atoms Rostas, Cossart, et al., 1974.
7D1 = 6.54E-4, H0 = -1.6E-8.
8Lifetime τ= 0.45 μs, corresponding to an absorption oscillator strength of 0.0078 Fink and Welge, 1964.
9Subband origins as defined by Rostas, Cossart, et al., 1974.
10Theoretical predictions Jordan, 1964, Cade, 1968, Liu, Legentil, et al., 1972, for a 1Δ confirmed by laser photoelectron spectrometry of PH-[see ref. Ishaque and Pearse, 1939 of PH-).
11Rotation sp. 15
12Constants deduced from isotope relations Rostas, Cossart, et al., 1974.
13Spin splitting constants λ0 = +2.212, γ0 = -0.0738; λ1 = +2.207, γ1 = -0.0726 Rostas, Cossart, et al., 1974.
14Adjusted theoretical value recommended by Meyer and Rosmus, 1975; see also Jordan, 1964, Cade and Huo, 1967, Liu, Legentil, et al., 1972.
