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

1Mostly R shaded heads in the region 10500 - 11800 cm-1; tentative analysis Afaf, 1950 gives ω'e = 862.9, ω'ex'e = 8.8; ω"e = 945.4, ω"ex"e = 8.6; uncertain.
2In a Ne matrix; ΔG'(1/2) = 872. For tentative assignments of gas phase emission bands in the same region see Gatterer, Junkes, et al., 1957.
3In a Ne matrix; ΔG'(1/2) = 836.
4The stronger R heads are at 28512.0, 28630.4, and 28790.5 cm-1.
5Absorption in stellar atmospheres Davis, 1947, Herbig, 1949, Davis and Keenan, 1969.
6Absorption in rare gas matrices Weltner and McLeod, 1965.
7Λ-type doubling, see Lindgren, 1973.
8ν00 (3Π1 - 3Δ1) = 18033.80, ν00 (3Π2 - 3Δ2) = 17804.1.
9B0 - B1; constants for v=2 in Tatum and Balfour, 1973.
10Dv values for v=1, 2 in Tatum and Balfour, 1973.
11{J'=0} relative to {J"=0}. A different definition was used in Tatum and Balfour, 1973.
12From the matrix (Ne) absorption spectrum, in good agreement with ω = 858 from Kratzer's relation.
13Λ-type doubling, Δ νfe = +0.00024J(J+1).
14{J'=0} relative to J"=0. A different definition was used in Balfour and Tatum, 1973.
15IR fundamental 19
16Thermochemical value (mass-spectrometry) Chupka, Berkowitz, et al., 1957, Brewer and Rosenblatt, 1969, Ackermann and Rauh, 1974, Murad and Hildenbrand, 1975.
17By electron impact Rauh and Ackermann, 1974, Murad and Hildenbrand, 1975.
18The energy of a 3Δ above X 1Σ is estimated Veits, Gurvich, et al., 1974 as 1700 ± 250 cm-1 from the temperature dependence of the integral absorption coefficients for the 0-0 bands of E-X and d-a. The triplet splittings derive from the observation Lindgren, 1973 of two satellite bands of β(0-0); see 8.
