Abstract：Using crossed molecular beam-chemiluminescence apparatus，visible chemiluminescence in the region of 300-900 nm was measured from the gas-phase reaction of microwave discharge of CF4 diluted in Ar with carbon disulfide at various pressures. The geometries and frequencies of possible reaction products were respectively investigated at the B3LYP/6-311++G(3df,2pd) and MP2/6-311+G(d,p) levels. Chemiluminescence spectrum was assigned to emission spectrum of the electronically excited states of F2S2. From the analyse of spectrum and reaction mechanism, it is proposed that carbon disulfur was dissociated by metastable Ar generated from microwave discharge. The electronically excited state of F2S2 was obtained from multistage reactions of the dissociative products with atoms F generated from microwave discharge.
