The gas-phase, ion molecule reaction between C,O:' and C,O, has been studied by both double-focusing and ion trap mass spectrometry, rationalized by the formation of a dimeric, odd electron cation IC6041+" which decomposes extensively through sequential CO losses giving rise to IC,O,l+. and IC,O,l+'
Upper limits of and were established for 4 Ο« 10 7 Ο« 10 cm molecule s the gas-phase reactions of H 2 O 2 with O 3 and NO, respectively. These reactions are too slow to explain features observed in the atmospheric vertical profile of H 2 O 2 .
Electron pulse radiolysis a t -298'K of 2 atm Hz containing 5 torr 0 2 produces HOz free radical whose disappearance by reaction (I), HOz + HOz -HzOz + 0 2 , is monitored by kinetic spectrophotometry a t 230.5 nm. Using a literature value for the HOz absorption cross section, the values k = 2.5 X cm
