Several orders of magnitude enhancements in the rate constants for three slow ion-molecule reactions with Hz have been observed when the H2 is vibrationally excited. The atomic cations C+, He+, and Ne+ were all observed to react near their respective Langevin rates with vibrationally excited HZ.

โฆ Synopsis
CRESU measurements of rate coefficients for the reactions of Het and C+ with HCI, SO2 and H2S are reported at 27 and 68 K. The results are compared with those obtained using three different ion-dipole theories and good agreement is obtained.
