Abstract

The spectral absorption due to parallel bands of nitrous oxide is computed in the region of the ν₃ fundamental for temperatures of 200°K and 300°K. The harmonic-oscillator approximation was used to compute the relative intensities of vibrational transitions for which no published data are available. The total integrated intensity of all of the transitions considered in the calculation was normalized to a value of 1850 cm⁻² atm⁻¹ at 300°K Values of the spectral absorption computed using the quasi-statistical band model and a half-width of 0.05 cm⁻¹ at 300°K are compared with published experimental data for various amounts of absorbing gas and total pressures; the results are seen to be in good agreement. A comparison of the spectral absorption obtained using the quasi-statistical band model and the strong-line and weak-line approximations is also given.
