Chemiluminescent reactions of samarium with several chlorinated hydrocarbons have been investigated under atomic beam-gas conditions. The chemiluminescent emission is attributed to the SmCl2emitter. The total cross-section σ , chemiluminescent cross-section σ CL and photon yields φ have been determined under single-collision conditions. It is observed that for saturated chlorocarbons the σ CL values increase as the degree of halogination increases. Planar, unsaturated molecules yield lower σ CL values than the saturated molecules. Simple RRK considerations show that the rates derived match qualitatively with experimental σ CL values and that the exoergicity of the reaction is an important factor in the reactive scattering process.
