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

โฆ Synopsis
The linear absorption cross-sections and photodissociation quantum yields for C F 3 N 0 have been measured at the wavelengths 694 3 and 632 8 nm (ruby and He-Ne lasers respectively) in a wide range of total pressure at T = 296 K The secondary reactions following the photolysis of C F 3 N 0 have been studied The rate constant of the CF3 + C F 3 N 0 reaction has been measured The results obtained show C F 3 N 0 photolysis be a convenient source of CFI radicals for kinetic studies 0 1996
