Abstract

Visible or ultraviolet luminescence is observed in the reactions of atomic fluorine with many organic and inorganic molecules. In most cases, the radiation is produced by reaction with fluorine atoms generated by electric discharge through either CF₄ or F₂-Ar mixtures, indicating that the luminescences are due neither to impurities nor to the very exothermic reactions of F₂. Some emissions, such as OH (A → X) in the reaction with H₂O, NH(A → X) with NH₃, and Cl₂(A → X) with Cl₂, are best explained as due to atomic combination. In other cases, this mechanism can be precluded by thermochemical arguments. With hydrocarbons, CH, C₂, CF, and CF₂ bands have been observed. The presence of oxygen is apparently not necessary to produce the CH emission. CO Cameron bands are one of the impurity-caused luminescences which have been observed in the hydrocarbon reactions. They are generated only when the atomic fluorine is produced from CF₄ and are possibly due to the reaction between atomic oxygen and CF.
