Moment Theories of Ion Motion and Ion-Neutral Reactions in Linear Traps

摘要

Moment theories of ion motion and reaction in ideal and stretched quadrupole ion traps are extended to the case of linear ion traps. Fortran and Mathematica computer programs based on these theories are developed. They are applied to the case of O⁺ ions moving through an Ar buffer gas containing a small amount of a reactive neutral, N₂. The rate coefficient predicted ab initio for a common set of trap parameters is 6.4±0.9×10^?13?cm³/s, which is large enough that it should be measureable.
