## Abstract A novel technique is described for forming groundβstate SO __X__^3^Ξ£^ο£Ώ^ radicals free of reactive impurities in a dischargeβflow system. Mass spectrometric detection of SO and ClO free radicals has been used to study the kinetics of the following reactions at 295 K: equation image
Fourier transform infrared spectroscopy was used to identify CH2CIOOH and HC(O)CI as products of the gas phase reaction of CH2CIO 2 radicals with HO 2 radicals. At 700 Torr and 295 \_ 2 K, branching ratios of kla//kl = 0.27 \_+ 0.05 and klb/k ) ffi 0.73 \_+ 0.12 were obtained for the CH2CIOOH formin
