Abstract
The paper describes an investigation of the reaction with ozone and the deactivation of O
2
(
1
Ʃ
+
g
). A flow technique was employed, and O
2
(
1
Ʃ
+
g
) was produced photochemically by the sequence of reactions: O
2
+
hv
(λ=1470Å)
→ O(
1
D
) + O(
3
P
), (4) O(
1
D
) + O
2
(
3
Ʃ
-
g
) → O
2
(
1
Ʃ
+
g
) + O(
3
P
). (5) The advantages achieved by this method of generation of the excited species are discussed. Rate constants were obtained for the reaction of O
2
(
1
Ʃ
+
g
) with ozone, and for its quenching by N
2
, and an estimate is made of the efficiency of wall deactivation. An upper limit is suggested for the quenching of O
2
(
1
Ʃ
+
g
) by molecular oxygen. The results are compared with those of earlier investigations, and the comparison is used to calculate the rate constant of the ‘energy-pooling’ reaction: O
2
(
1
∆
g
) + O
2
(
1
∆
g
) → O
2
(
1
Ʃ
+
g
) + O
2
(
3
Ʃ
-
g
). (1) Measurement of the concentrations of O
2
(
1
Ʃ
+
g
) and of atomic oxygen formed on photolysis allows the efficiency of the energy transfer process (5) to be assessed relative to the efficiency of quenching by O
2
, N
2
or Ar. The several rate constants measured or estimated are tabulated at the end of the paper in table 3.
