Haloacetyl peroxynitrates are intermediates in the atmospheric degradation of a number of haloethanes. In this work, thermal decomposition rate constants of CF3C(0)02N02, CClFzC(0)02N02, CC12FC(0)02N02, and CC13C(0)02N02 have been determined in a temperature controlled 420 1 reaction chamber. Peroxy

## Abstract Data in both directions for the title reaction have been statistically fit (weighted nonlinear least squares) to the different formalisms used by the NASA and IUPAC data evaluation panels. The data are well represented by either formalism. Master equation/RRKM methods were then employed
Rate constants for the reactions of OH radicals and Cl atoms with CH,CH,NO>, CH,CH,CH,NO,, CH3CH2CH2CHzN02, and CH,CH2CH2CH,CH2N02 have been determined at 295+3 K and a total pressure of approximately 1 atm. The OH rate data were obtained using both the absolute rate technique of pulse radiolysis co
