Effect of Collision Energy and Vibrational Excitation on Endothermic Ion-Molecule Reactions

摘要

This thesis is divided into two major parts. In the first part an experimental study of proton and deuteron transfer in H sub 2+ + He and HD exp + + He has been carried out as a function of kinetic and vibrational energy. The data gives evidence that at lower kinetic energies, the spectator stripping mechanism indeed plays an important role when H sub 2+ or HD exp + is vibrationally excited. The second half of this thesis examines the relative efficiencies between the excitation of C-C stretching vibration and collision energy on the promotion of the H atom transfer reaction of C sub 2 H sub 2+ + H sub 2 yields C sub 2 H sub 3+ + H.
