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.

1X-ray absorption (3ssigma larrow 1sN).
2X-ray absorption and emission (1pig lrarrow 1sN), broad peak. 119
3Absorption cross sections 140000-500000 cm-1 Lee, Carlson, et al., 1973, Watson, Lang, et al., 1973.
4From high-energy electron impact spectroscopy.
5First two members of Codling's Rydberg series. 120
6Longward of the apparent emission "lines" are close-lying fairly sharp absorption "lines" Ogawa and Tanaka, 1962. Both features belong to the same Fano shape produced by the interaction of the series of Rydberg levels with the continuum joining on to the A 2Pi (or, less likely, X 2Sigma) limit.
7Similar series with v'=1.
8The first three members at 138330, 144090, 146690 cm-1 are very broad (presumably because of preionization), the higher members are sharper and shaded to the red. No rotational structure has been resolved. Preionization also observed by electron spectroscopy Hicks, Comer, et al., 1973, Wilden, Hicks, et al., 1976.
9Oscillator strengths from absorption coefficients: f(m=3,4,..) = 0.0131, 0.0053, ... Cook and Ogawa, 1970.
10Similar series for v'=l [observed to n=45 (2Pi1/2) and n*=40.2 (2Pi3/2)] and for v'=2...7 Yoshino, Ogawa, et al., 1976.
11Corresponding series in 15N2 Ogawa, 1964.
12Preionization observed in photoionization studies Cook and Ogawa, 1965, Comes and Weber, 1969, Carter and Berkowitz, 1973.
13Preionization in absorption series having v'=1...4 was observed in active nitrogen using the photoionization technique Cook and McNeal, 1972.
14These designations should not be confused with the older designations of component states of b 1Piu and b' 1Sigmau+.

27Only v=0 [perturbed by c'6(v=1)] is sharp: bands with v'= 1,2,3 are diffuse owing to predissociation or preionization (levels with v > 2 are above the first ionization potential).
28DeltaG(3/2) = 2119.7, see 29.
29Strong homogeneous perturbations with the higher vibrational levels (v geq 18) of b' 1Sigmau+ Carroll and Yoshino, 1972. The B0 value is an effective value at low J: Beff(v=1) = 1.285, Beff(v=2)= 1.173. In addition, there are heterogeneous interactions with the close- lying levels of c4 1Piu. For deperturbed constants see Leoni and Dressler, 1972, Leoni, 1972.
