The Spectrum and Transmission of Ammonia under Jovian Conditions

Abstract
The theory and data for calculating the positions, intensifies, and half-widths of the spectral lines of ammonia with frequencies −1 are described. The ground state rotation, μ2, 2ν2− ν2, and the rotation-inversion bands of ν2 and 2ν2 were included. The quantities necessary to fit a random-exponential band model are tabulated in 25 cm−1 intervals for temperatures from 100 to 225K at 25K intervals. Temperature and pressure corrections to the half-widths for application to the Jovian atmosphere are given. Consideration of the line shape suggests that opacity in the 200–700 cm−1, interval will be due to local lines, except possibly at very low temperatures and high pressures.
