✦ Synopsis

The absolute rate constants have been measured for several gas-phase chlorine atommolecule reactions a t 25OC by resonance fluorescence. These reactions and their corre- sponding rate constants in units of cm3 mole-' sec-l are:

The effects of varying the substrate pressure, total pressure, light intensity and chlorineatom source on the value of the bimolecular rate constants have been investigated for all these reactions. Conditions under which no competing side reaction occurs were established and the reported rate constants were measured under these conditions. For reactions (2), ( 5), ( 6) , (7), and 8, there is a discrepancy of a factor of two between the rate constants ntcasured in this work and values in the literature; it is suggested that this is due to an error in the previously measured value of kCHa/kHa upon which the relative measurements in the literature ultimately depend.
