The ion-molecule reaction of O+ with N-2 measured down to 23 K
The rate constant of the O+ + N-2 ion-molecule reaction has been measured from 225 down to 23 K with the CRESU technique. It has been found that the rate slightly increases when temperature decreases down to 23 K but remains two orders of magnitude below the Langevin rate. This indicates that the reaction does not occur via a long lived complex. (C) 2003 Elsevier Science B.V. All rights reserved.
