Abstract:
Using a radio-frequency ion trap to study ion–molecule reactions under isolated conditions, we report a direct experimental determination of reaction rate constants for the sequential oxidation of iodine anions by ozone at room temperature (300 K). The results are R1: I − + O 3 → IO − + O 2 , k 1 = (7 ± 2) × 10 −12 cm 3 s −1 ; R2: IO − + O 3 → IO 2 − + O 2 , k 2 = (10 ± 2) × 10 −9 cm 3 s −1 ; R3: IO 2 − + O 3 → IO 3 − + O 2 , k 3 = (16 ± 2) × 10 −9 cm 3 s −1 . More oxidized forms such as IO 4 − and IO 5 − were not observed. Additionally, we performed quantum chemical calculations to elucidate the energetics of these oxidation reactions.
