Ion Diffusion

Importance of Ion Diffusion Study

Ion diffusion and mobility data in a gas theoretically and experimentally are important. First, experimental data of ion mobility provides information to understand the ion-molecule interactions. Also it is used to calculate the ion-ion recombination coefficients and the rate of dispersion in the gas due to the ion mutual repulsion.Finally, diffusion and mobility data give information to undestand the electrical discharges in gases.

Although A lot of data has been collected on the ion transport in gas in the last decade, recent measurents show a lot of incorrect data due to ignore the change in the ion identity through a chemical interaction as the ion travels in a gas.
