State-Resolved Dynamics of Ion-Molecule Reactions in a Flowing Afterglow
Abstract
The dynamics and kinetics of ion-molecule collision processes have been explored in flowing afterglow, flow-drift and single collision instruments using laser-induced fluorescence and Doppler resolved laser probing. The rate coefficients and branching ratio for the atmospherically important reaction, N2++o, have been studied. The rotational alignment of N2+ induced by collisions with helium has been characterized in uniform electric drift fields; a theoretical treatment has been developed to relate the observed alignment to the individual tensor cross sections in the collisions. The mobility and velocity distribution of Ba+ drifted in helium have been determined using single frequency laser-induced fluorescence. The vibrational and rotational product state distributions of the Penning ionization reaction, Ne + N2, have been characterized under single collision conditions. Keywords: Atmospheric chemistry, Penning ionization, Nitrogen oxygen, Barium, Neon.
