The kinetics of the acqueous-phase reactions of the free radicals .OH, .Cl,, and SO; . with the halogenated acetates, CHzFCOO-, CHF2COO-, CF3COO-, and with CHzClC00-, CHClzC00-, CC13COOwere investigated. Generally, the reactivity decreases with increasing halogen substitution and is in the order k(.

Reactions of HCCCO and NCCO radicals with O 2 have been studied by a combination of pulsed laser photolysis and photoionization mass spectrometry. HCCCO was produced by 193-nm photolysis of methylpropiolate or 3-butyn-2-one, and NCCO was formed by 193-nm photolysis of acetylcyanide. The rate constan
Rate constants have been measured for the reactions of four hydrocarbon radicals with O2 in the gas phase at room temperature. Laser flash photolysis was used to generate low concentrations of radicals. A photoionization mass spectrometer followed the radical loss as a function of time. The measured
