Resonant fluorescent scattering of solar radiation by the fourth positive band system of CO.
The resonant fluorescent scattering equations for a diatomic molecule are developed as a function of temperature, column density, and optical thickness of absorbing rotation lines. The equations are solved numerically for absorption of solar vacuum uv radiation by the carbon monoxide fourth positive band system. Saturation column densities are determined and computer spectra are presented. It is shown that at high column densities, fluorescent scattering of the solar Lyman a line by the (14,0) band constitutes a significant portion of the total absorption.
