Kinetics of the reactions of CF3O2 with OH, HO2 and H
Abstract
The kinetics of the reactions:
CF
3
O
2
+OH→products (1),
CF
3
O
2
+HO
2
→products (2)
and CF
3
O
2
+H→CF
3
O+OH
(3), have been investigated using a discharge fast-flow
tube, at T=296±1 K and
P=ca. 2 Torr. Two detection systems were
used: laser-induced fluorescence of NO
2
produced
from the titration of CF
3
O
2
with NO,
and resonance fluorescence of OH. The rate constants (in
cm
3
molecule
-1
s

) were
found to be,
k
1
=(4.0±0.6)×10
-11
, k
2
⩽3×10
-12
and
k
3
=(1.1±0.3)×10
-
10
. Experimental evidence suggests that the likely
products of the reaction of CF
3
O
2
with
OH are HO
2
and CF
3
O.
