The pyrolysis of CF,H mixture, highly diluted with Ar, was studied over the temperature range 1150-I 570 K at pressures 1.5-2.6 atm behind reflected shock waves. The mechanism and the rate constant of CFXH pyrolysis at the high temperatures were discussed. The pyrolysis of CFgH was found to be inter

โฆ Synopsis
The UV absorption spectrum and the dissociation rate of CF$ in Ar have been measured in shock waves. For [Ar] = 1.7 X 10m5 mol cmW3, the dissociation rate constant k/[Ar] = 1.5 x 1016 exp(-168 kJ moi-'/RT) cm? mol -l s-l_ The absorption cross section 0 = aF" [tgh(ee/ZT)] 8, = 409 K, A"o = 2370 cm-l t'* exp{-tgb(Be/2T) {[w -vo(T)] /Avo)2)with upay = 8.05 x lo-l9 cm* andve(T) =(38017 -417T/300 K) cm-'.

The thermal decomposition of SO, and of the primary dissociation product SO have been studied in shock waves by the uv absorption technique. The controversy about SO, dissociation data from uv absorption signals was resolved and attributed to the extensive overlap of SO, and SO uv absorption spectra
