โฆ Synopsis
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.

We present calculations of the rate constants for the title reactions on a new accurate potential energy surface with a 9.65 kcal mol-barrier and a carefully fitted long-range attraction. The low-temperature thermal rate constant decreases from the previously calculated value, corresponding to a sur
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.
