Progress reports are presented for the following research topics: reaction of chlorofluoromethyl radicals, CF/sub 2/Cl, with O/sub 2/; kinetics of highly vibrational excited molecules; kinetics of CH/sub 2/(/sup 1/B/sub 1/) reactions; and flash photolysis with time resolved mass spectroscopy. Some of the highlights are: (1) information on the mechanism of the reaction of CF/sub 2/Cl radicals has been obtained, including evidence that CF/sub 2/ClO radicals can oxidize CO; (2) CF/sub 2/Cl radicals were produced by photooxidation of 1,3-dichlorotetrafluoroacetone (DTA) at 313 nm; (3) investigation of the DTA-O/sub 2/ photolysis system using flash spectroscopy continued and observations are summarized; (4) results from laser flash photolysis-absorption spectroscopy show that collisional deactivation of toluene, ethylcycloheptatriene and isopropylcycloheptatriene occurs by removal of relatively small amounts of energy; (5) flashlamp pumped dye laser was used as a 400 nm excitation source to photolyze diazomethane, CH/sub 2/N/sub 2/. The photon energy was sufficient to produce the second excited state of methylene, CH/sub 2/(/sup 1/B/sub 1/). (ATT)
