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

## Abstract Rate constants for the gasโphase reactions of CH~3~OCH~2~CF~3~ (__k__~1~), CH~3~OCH~3~ (__k__~2~), CH~3~OCH~2~CH~3~ (__k__~3~), and CH~3~CH~2~OCH~2~CH~3~ (__k__~4~) with NO~3~ radicals were determined by means of a relative rate method at 298 K. NO~3~ radicals were prepared by thermal d
Using a pulse-radiolysis transient UV-VIS absorption system, rate constants for the reactions of F atoms with CH 3 CHO (1) and CH 3 CO radicals with O 2 (2) and NO (3) at 295 K and 1000 mbar total pressure of SF 6 was determined to be By monitoring the for-ฯช12 ฯช11 3 ฯช1 ฯช1 (4.4 ฯฎ 0.7) ฯซ 10 , and k ฯญ
The rate constants for the reactions of OH radicals with CH 3 OCF 2 CF 3 , CH 3 OCF 2 CF 2 CF 3 , and CH 3 OCF(CF 3 ) 2 have been measured over the temperature range 250-430 K. Kinetic measurements have been carried out using the flash photolysis, laser photolysis, and discharge flow methods combine
Disproportionation/combination rate constant ratios, k , / k , , have been measured for the collision between CF3CH2CH2 and CF3 radicals to be 0.022 ? 0 002 and for CF3CH2CH2 and CF3CH2CH2 radicals to be 0.100 IT 0.002. Comparison to previous work from this laboratory for the reaction of CF3CH2CHCI
