Interaction between the ion dipole and the ion-induced dipole in reactions of the polar ion ArH+3

Article abstract of DOI:10.1063/1.466691

The reactions of the highly polar ion ArH⁺3 with the nonpolar neutrals Xe, Kr, CH4, CO, NO, O2, and N2 and with the polar neutrals SO2, H2O, NH3, CH3I, and C2H5I have been investigated in a selected ion flow drift tube experiment at near thermal conditions.The rate coefficients obtained have typically 15percent-35percent larger values than the collisional limiting values k_L and k_ADO obtained by the Langevin and ADO (average dipole orientation) theory, respectively.These data are explained on the basis of the interaction between the dipole of ArH⁺3 and the ion-induced dipole and the permenent dipole, respectively, of the neutral reactants.Rate coefficients for the reactions of H⁺3 with the above neutrals were also obtained for comparison, as well as the zero field mobility of ArH⁺3 in helium being (18.5+/-1.5) cm²/V s.The ion KrD⁺3 (KrH⁺3) was detected unambiguously for the first time.Its dissociation energy is larger than 0.29 eV which is the lower limit of the dissociation energy of ArH⁺3.
