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.
The rate c&Want and the product distriblition for the reaction of D; w&h I& has been masured as a function of the Dz vibrational energy. in these experiments a mass analyzed bfzam of D3 ions is de&crated to le& than 0.1 eV and is subsequently injected into an ion cyclotron resonance (ICR) cell where
The rate constants k,, k2 and t for the reactions of N( 'D) atoms with I-I>, HF, and 02, measured at room temperature in a discharge-flow atomic-resonance-absorption apparatus, have been determined to be (1.8 kO.8) x IO-'\*, (1.0\_+0.3) x lo-'" and (6.6 f 1.0) X lo-l2 cm3 s-l, respectively.

Detailed rate constants of the H + H,( (1 < 10) reaction have been calculated with the aim of investigating the efficiency of deactivation processes and their dependence upon the vlbrational excitation of the hydrogen molecule.
