Abstract : The report briefly summarizes research concerning the chemical compositon and stability of planetary atmospheres, - primarily oxygenic atmospheres such as that of the earth, but potentially equally important in other atmospheres such as that of Venus. The atmosphere is a massive hydrodynamic system driven by photochemical energy sources. Light absorbing compounds, such as ozone, have a lamillar distribution which stems directly from the detailed mechanism of the photochemical reactions. A reliable model of this chemical distribution as a steady state photochemical system requires a self consistent theoretical and phenomenological understanding of all of the rate parameters of the individual processes which occur. Gas phase reactions of systems containing oxygen are complicated in a fundamental way by the formation of molecules and atoms in long lived electronic excited states. (Author)
