Studies in chemical reactivity. Progress report, 30 November 1981 to 1 October 1982

Progress reports are presented for the following research topics: reaction of chlorofluoromethyl radicals, CF2Cl, with O2; kinetics of highly vibrational excited molecules; kinetics of CH2(1B1) reactions; and flash photolysis with time resolved mass spectroscopy. Some of the highlights are: (1) information on the mechanism of the reaction of CF2Cl radicals has been obtained, including evidence that CF2ClO radicals can oxidize CO; (2) CF2Cl radicals were produced by photooxidation of 1,3-dichlorotetrafluoroacetone (DTA) at 313 nm; (3) investigation of the DTA-O2 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, CH2N2. The photon energy was sufficient to produce the second excited state of methylene, CH2(1B1)
