The potential depletion of ozone concentrations in the stratosphere by man's use of halocarbons has received considerable attention. The halocarbons (primarily CF2Cl2 and CFCl3) released on the Earth's surface eventually reach the stratosphere by diffusion where they undergo photodissociation releasing chlorine atoms. Once free in the stratosphere, the chlorine atoms can catalytically react to deplete stratospheric ozone. Preliminary calculations indicate a substantial (7-10 percent) reduction of the stratospheric ozone layer with possible serious consequences for life on the Earth's surface. In order to improve the reliability of these predictions, much research involving stratospheric species has been undertaken. This paper describes the results of three independent shock tube investigations of the properties of molecular species of importance in the stratospheric ozone depletion problem, and thereby demonstrates the versatility and usefulness of shock tubes to current research.
