✦ Synopsis

The relative rate technique has been used to investigate the kinetics of the reaction of Cl atoms with carbon disultide, CS,, at 700 Torr total pressure of air at 298 K. The decay rate of CSz was measured relative to CHI, CH,CI and CHFQ For experiments using CH4 and CHFI references, the decay rate of CSz was dependent on the ratio of the concentration of the reference to that of CS2. We ascribe this behavior to the generation of OH radicals in the system leading to complicated secondary chemistry. From experiments using CHFrCI we are able to assign an upper limit of 4 x 1O-'5 cm3 molecule-' s-' for the overall reaction, Cl t C&products.
