Variation of the absorption spectrum of molecular fluorine in the temperature range 300-1000 K
Abstract
Kinetic spectroscopy was used to measure changes in the spectral absorption coefficient of F2 during heating to different temperatures in the 300-1000 K range. The pulse heating was the result of a rapid photochemical reaction of fluorine with a predetermined amount of hydrogen. The smallest change in the spectral absorption coefficient over the temperature range studied was observed at 326 nm. The strong temperature dependence of the absorption coefficient permits direct determination of the temperature of a reaction mixture of fluorine and hydrogen.
